chalcopyrite. These ores are often refractory, as the gold is encapsulated within the sulfide matrix. In order to recover the gold, the host matrix must be destroyed. Over the past 100 years, roasting or smelting has been the dominant method for oxidising sulfide bearing gold ores and concentrates. However, with the cost associated with treating SO

Effect of Gold Particle Size on Rate of Dissolution
When coarse free gold occurs in ores, the usual practice is to remove it by means of gold traps, jigs, blankets, etc. ahead of cyanidation.Otherwise, these coarse particles might not be completely dissolved in the time available for cyanidation. Another practice which reduces the size of the gold particles going to cyanidation is the grinding …

Intrusive related gold usually also contains copper, and is often associated with tin and tungsten, and rarely molybdenum, antimony and uranium. Intrusive-related gold deposits rely on gold existing in the fluids associated with the magma (White, 2001), and the inevitable discharge of thesehydrothermal fluids into the wall-rocks (Lowenstern, 2001).

How Is Gold Formed? Origins and Process
Nevertheless, gold accounts for a few parts per billion of the mass of the Earth's crust. While it's not economically feasible to extract much gold, there are about 1 million tons of gold in the top kilometer of the Earth's surface. The abundance of gold in the mantle and core is unknown, but it greatly exceeds the amount in the crust.
