Methods of Gold Mining Geology In

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

How is gold mined?

Gold is mined by 4 different methods. Placer mining, hard rock mining, byproduct mining and by processing gold ore. Each of these categories has it's own unique methods of extracting the gold from the surrounding materials. In placer mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging.

Newmont Corporation About Us About Mining The Mining

Searching for gold is a complex, scientific and time-intensive process. With odds of only one in 3,000 discoveries leading to mine development, and only 10 percent of the world’s gold deposits containing enough gold to mine, exploration can be wearisome and expensive.

Hydraulic Mining. Historic Gold Mining Methods of California

Hydraulic Mining was a gold recovery method that was used during many of the gold rushes around the world during the 1800’s. It was used extensively in California's Mother Lode county during the famous gold rush there. One of the problems that the early California gold miners faced with basic placer mining was the amount of manual labor that was required to process the gravels.
