A gold bar is stamped with a serial number at a U.S. refinery in 2001. The bar, which weighed about 40 pounds (18 kilograms), was one of nine gold bars poured that day. Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
