A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

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 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson Deep, at that time the ...

The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise. First, geologists know more about how gold ...

Most forms of gold mining involve moving massive amounts of soil and rock, which can be detrimental to the surrounding wildlife habitat. The U.S. Environmental Protection Agency estimates that the development of a proposed gold and copper mine in Alaska's Bristol Bay would destroy at least 24 miles of streams that support the world's largest sockeye salmon fishery.

However, to date, only small quantities have been found in some of the state's bedrock (the solid rock under the soil) and in the gravels at the bottom of some streams (as placer deposits). When gold is found in the bedrock, it usually occurs in veins – long, narrow mineral rich "streaks." It is removed by breaking up the rock and ...
