Gold mining is the resource extraction of gold by mining.
As of 2016, the world's largest gold producer was China with 463.7 tonnes. The second-largest producer, Australia, mined 287.3 tonnes in the same year, followed by Russia with 274.4 tonnes.
It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old. A group of German and Georgian archaeologists claims the Sakdrisi site in southern Georgia, dating to the 3rd or 4th millennium BC, may be the world's oldest known gold mine.
Bronze age gold objects are plentiful, especially in Ireland and Spain, and there are several well known possible sources. Romans used hydraulic mining methods, such as hushing and ground sluicing on a large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas. Mining was under the control of the state but the mines may have been leased to civilian contractors some time later. The gold served as the primary medium of exchange within the empire, and was an important motive in the Roman invasion of Britain by Claudius in the first century AD, although there is only one known Roman gold mine at Dolaucothi in west Wales. Gold was a prime motivation for the campaign in Dacia when the Romans invaded Transylvania in what is now modern Romania in the second century AD. The legions were led by the emperor Trajan, and their exploits are shown on Trajan's Column in Rome and the several reproductions of the column elsewhere (such as the Victoria and Albert Museum in London). Under the Eastern Roman Empire Emperor Justinian's rule, gold was mined in the Balkans, Anatolia, Armenia, Egypt, and Nubia.
In the area of the Kolar Gold Fields in Bangarpet Taluk, Kolar District of Karnataka state, India, gold was first mined prior to the 2nd and 3rd century AD by digging small pits. (Golden objects found in Harappa and Mohenjo-daro have been traced to Kolar through the analysis of impurities — the impurities include 11% silver concentration, found only in KGF ore.) The Champion reef at the Kolar gold fields was mined to a depth of 50 metres (160 ft) during the Gupta period in the fifth century AD. During the Chola period in the 9th and 10th century AD, the scale of the operation grew. The metal continued to be mined by the eleventh century kings of South India, the Vijayanagara Empire from 1336 to 1560, and later by Tipu Sultan, the king of Mysore state and the British. It is estimated that the total gold production in Karnataka to date is 1000 tons.
The mining of the Hungarian deposit (present-day Slovakia) primarily around Kremnica was the largest of the Medieval period in Europe.
During the 19th century, numerous gold rushes in remote regions around the globe caused large migrations of miners, such as the California Gold Rush of 1849, the Victorian Gold Rush, and the Klondike Gold Rush. The discovery of gold in the Witwatersrand led to the Second Boer War and ultimately the founding of South Africa.
The Carlin Trend of Nevada, U.S., was discovered in 1961. Official estimates indicate that total world gold production since the beginning of civilization has been 4,970,000,000 troy ounces (155,000 t) and total Nevada production is three percent of that, which ranks Nevada as one of the Earth's primary gold producing regions.
As of 2015, the data mining bias largest gold producer by far was China with 455 tonnes/year. The second-largest producer, Australia, mined 270 tonnes in the same year, followed by Russia with 250 tonnes.
Despite the decreasing gold content of ores, the production is increasing. This can be achieved with industrial installations, and new process, like hydrometallurgy.
Main article: Placer mining
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
Main article: Gold panning
Gold panning is mini gold mining a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called mini gold mining deposits.
Gold panning is the easiest and quickest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability.
Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and small-scale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold-bearing material is placed at the top of the box. The material is carried by the current through the volt where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings.
Larger commercial placer mining operations employ screening plants, or trommels, to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. These operations typically include diesel powered, earth moving equipment, including excavators, bulldozers, wheel loaders, and rock trucks.
Main article: Gold dredge
Although this method has largely been replaced by modern methods, some dredging is done by small-scale miners using suction dredges. These are small machines that float on the water and are usually operated by one or two people. A suction dredge consists of a sluice box supported by pontoons, attached to a suction hose which is controlled by a miner working beneath the water.
State dredging permits in many of the United States gold dredging areas specify a seasonal time period and area closures to avoid conflicts between dredgers and the spawning time of fish populations. Some states, such as Montana, require an extensive permitting procedure, including permits from the U.S. Corps of Engineers, the Montana Department of Environmental Quality, and the local county water quality boards.
Some large suction dredges (100 horsepower (75 kW) & 250 mm (10 in)) are used in commercial production throughout the world. Small suction dredges are much more efficient at mini gold mining smaller bitcoin iphone mining than the old bucket line, mini gold mining. This has improved the chances of finding gold. Smaller dredges mini gold mining 50-to-100-millimetre (2 to 4 in) suction tubes are used to sample areas behind boulders and along potential pay streaks, until "colour" (gold) appears.
Other larger scale dredging operations take place on exposed river gravel bars at seasonal low water. These operations typically use a land based excavator to feed a gravel screening plant and sluice box floating in a temporary pond. The pond is excavated in the gravel bar and filled from the natural water table. powerpoint mining gravel is excavated from the front face of the pond and processed through the floating plant, with the gold trapped in the onboard sluice box and tailings stacked behind the plant, steadily filling in the back of the pond as the operation moves forward. This type of gold mining is characterized by its low cost, as each rock is moved only once. It also has low environmental impact, mini gold mining, as no stripping of vegetation or overburden is necessary, and all process water is fully recycled. Such operations are typical on New Zealand's South Island and in the Klondike region of Canada.
Also called a cradle, it uses riffles located in a high-walled box to trap gold in a similar manner to the sluice box. A rocker box uses less water than a sluice box and is well suited for areas where water is limited. A rocking motion provides the water movement needed for the gravity separation of gold in placer material.
Hard rock mining
Main articles: Quartz reef mining and Carlin-type gold deposit
Hard rock gold mining extracts gold encased in rock, rather than emc2 mining in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to mini gold mining metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of mini gold mining workers. The first such mine to receive air conditioning was Robinson Deep, at that time the deepest mine in the world for any mineral.
By-product gold mining
Gold is also produced by mining in which it is not the principal product. Large copper mines, such as the Bingham Canyon mine in Utah, often mini gold mining considerable amounts of gold and other metals along with copper. Some sand and gravel pits, such as those around Denver, Colorado, may recover small amounts of gold in their wash operations. The largest producing gold mine in the world, the Grasberg mine in Papua, Indonesia, is primarily a copper mine.
A modest amount of precious metal is a by-product of sodium production.
Gold ore processing
Main articles: Gold extraction and Gold parting
In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used.
Main article: Gold cyanidation
Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is added to precipitate out residual zinc as well as the silver and gold metals. The zinc is removed with sulfuric acid, leaving a silver or gold sludge that is generally smelted into an ingot then shipped to a metals refinery for final processing into 99.9999% pure metals.
Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area, that fifteen grams of it has the equivalent surface area of the Melbourne Cricket Ground (18,100 square metres (195,000 sq ft)), mini gold mining. The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution, mini gold mining. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
The technique using dissolution with alkaline cyanide has been highly developed over recent years. It is particularly appropriate for low grade gold and silver ore processing (e.g. mini gold mining than 5 ppm gold) but its use is not restricted to such ores. There are many environmental hazards associated with this extraction method, largely due to the mini gold mining acute toxicity of the cyanide compounds mini gold mining. A major start mining free of this hazard was demonstrated in the 2000 Baia Mare cyanide spill, when a break in holding pond dam at a mine waste reprocessing facility near Baia Mare in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into the Tisza River. As a consequence, most countries now have strict regulations for cyanide in plant discharges, and plants tourmaline mining include a specific cyanide-destruction step before discharging their tailings to a storage facility.
Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in small scale, often clandestine, gold prospecting. It is estimated that 45,000 metric tons of mercury used in California for placer mining have not been recovered.
While most of the gold is produced by major corporations, tens of thousands of people work independently in smaller, artisan operations, in some cases illegally. In Ghana, for instance, the galamseys are estimated to number 20,000 to 50,000. In neighboring francophone countries, such workers are called orpailleurs. In Brazil, such workers are called garimpeiros.
The high risk of such ventures was seen in the collapse of an illegal mine at Dompoase, Ashanti Region, Ghana, on 12 November 2009, when 18 workers were killed, z270 killer sli mining 13 women. Many women work at such mines as porters. It was the worst mining disaster in Ghanaian history.
In order to maximize gold extraction, mercury is often used to amalgamate with the metal. The gold is produced by boiling away the mercury from the amalgam. Mercury is effective in extracting very small gold particles, but the process is hazardous due to the toxicity of mercury vapour.
Especially after the Minamata Convention has been ratified, mini gold mining, there are initiatives to replace or reduce the use and emissions of mercury in the extraction of gold.
Main article: Largest gold companies
Barrick Gold, Goldcorp, Newmont Mining Corporation, Newcrest Mining, mini gold mining, and AngloGold Ashanti are the world's five largest gold mining companies by market capitalisation in 2008.
Gold mining can significantly alter the natural environment. For example, gold mining activities in tropical forests are increasingly causing deforestation along rivers and in remote areas rich in biodiversity. Other gold mining impacts, particularly in aquatic systems with residual cyanide or mercury (used in the recovery of gold from ore), can be highly toxic mini gold mining people and wildlife even at relatively low concentrations.
However, there are clear moves by many in the non-governmental organization community to encourage more environmentally friendly and sustainable business practices in the mining industry. The primary way this is being achieved is via the promotion of so-called 'clean' or 'ethical' gold. The aim is to get all end users/retailers of gold to adhere to set of principles that encourage sustainable mining. Campaigns such as 'No Dirty Gold' are driving the message that the mining industry is harmful (for the reasons noted above), and so must be cleaned up. Also, NGOs are urging the industry and consumers to buy sustainably produced gold. Human Rights Watch produced a report that outlines some of challenges faced globally, noting that: "Thousands of children in the Philippines risk their lives every day mining gold. Children work in unstable 25-meter-deep pits that could collapse at any moment. They mini gold mining gold underwater, along the shore, mini gold mining, or in rivers, with oxygen tubes in their mouths. They also process gold with mercury, a toxic metal, risking irreversible health damage from mercury poisoning." Along with many other reports and articles, this has had the effect of spurring retailers and industry bodies to move toward sustainable gold. Cointellect mining, the World Jewellery Confederation insists that it does all it can to "Deliver a Sustainable and Responsible Jewellery Industry." Likewise, the use of so-called Fairtrade gold is growing; with businesses moving over to, or at least offering, this option at both retail and wholesale levels.

|The Mini Trommel is an extremely portable and versatile unit that can be towed behind an ATV. |
The unit has a wide stance and good center of gravity with good ground clearance which is perfect
for difficult terrain. The durable pneumatic tires are 15.5 inch in diameter and come with sealed
bearings [ .Also offered is an optional ATV tire/axle combination for even better maneuverability
off road ]. The tow bar is removable by way of a 1/2 inch hitch pin. The Mini can be easily set up
and ready to run in a matter of minutes. The legs are fully adjustable in height to compensate for
varying terrain & also to adjust material processing rates.
The Mini can be disassembled without tools into its major components in under 1 minute
to facilitate loading & unloading by one person into/out of a standard truck bed or trailer, this
also enables packing into remote locations as well. The all steel frame is fully triangulated for
maximum durability while still remaining light weight enough to maneuver the unit by hand.
The unit is powered by either a Gas driven [ STANDARD MODEL ] or your choice of TWO
different Diesel driven options OR an Electric driven option is available as well. The motor comes
with a heavy duty skid plate underneath.
The fuel tank is remote mounted & comes with an inline fuel filter. The heavy duty positive chain
drive system utilizes sealed unit bearings and is fully adjustable in tension both at the motor as
well as the barrel. The drive system is a variable 6-13 RPM design and is strong enough to process
full loads at idle.
The Feed Hopper comes with a full spray bar system with a "pusher jet" for quick and easy
processing of materials as well as excellent material washing. It is fully removable with four 3/8
inch locking pins and can be quickly exchanged with either of our optional quick release 3 inch or
4 inch Dredge Adapters. The removable Dredge Adapter is designed to feed directly into the
barrel without the need for the Feed Hopper.
The 2-stage barrel is 6 foot in total length and 15 inch in diameter. The "Scrubber" section of the
barrel is 24 inch in length and is loaded with a full array of slurry "turn plates" [material lifting
bars] as well as slurry dams, both of which enable excellent clay and cemented gravel
break down and washing. This unit has one of the best working "Scrubber" sections available for
a unit this size and helps level out the material "surging" that is common with shorter barrels.
The screen portion of the barrel is 36 inch in length and is manufactured from perforated steel
[punch plate] with the highest percentage of "open area" available to help produce some of the
highest Tons per Hour numbers available to the open market. Classification hole size is 1/2 inch
standard with other sizing options available upon request. The tail section of the barrel contains
two of our "Nugget rings" for retention of over sized values. Not shown is the safety cover over
the gearing on the barrel.
The water delivery system consists of an adjustable angle- full length spray bar inside the barrel
that is easily removable by way of two quick release pull pins and is fully adjustable in flow rate
with its own gate valve. The Feed Hopper also contains a perimeter spray bar that is also easily
removable as well as adjustable in angle and also comes with its own gate valve for flow
adjustment. The Hopper spray bar also contains a "pusher" jet to aid in consistent material feed
when shoveling or feeding by bucket. The Hopper also has a quick release safety cover to protect
the spray bar from damage and provides a sturdy place to "bang" the shovel clean or rest a
bucket. This unit will easily process 2- 3.5 full five gallon buckets of material per minute so we
felt there was no real need for a "bucket rest" feature in or on the Feed Hopper for this unit
[though available as an option]. The water distribution box also has a connection for a wash out
The included sluice box measures in at 60 inches long by 12 inch wide and is more than adequate
at keeping up with the feed rate associated with this Trommel unit. Standard riffle design is a
"70/30" mix of 3# Gratex [large expanded] and Hungarian style riffles that have varied spacing
and angles to ensure great recovery percentages of values. We can also custom tailor the sluice
recovery system to the specific recovery needs of your particular operation as well.
Also included with the sluice is one of our infamous "Bubble Brushes" to virtually eliminate
bubbles in the slurry and also provides a smooth flow transition to the riffles. The sluice comes
with a full square tube "ladder" style frame and fully adjustable legs to enable ease of
adjustment of sluice angle.
When setting up for operation, the sluice can be mounted on either side of the Trommel unit with
a single 3/8 inch grade 8 quick release mounting pin which allows for ease of adjustment to most
any angle. When in transport the Sluice box can be mounted to the top of the Trommel frame and
strapped down for safety.
