8 Types of Gold Ore- Properties and Ways to Process |

2021-10-28 · Properties of gold sulfide ore Gold sulfide ore is the inorganic compound with the formula Au2S. It is the principal sulfide of gold and decomposes to gold metal and elemental sulfur, illustrating the "nobility" of gold. In nature, the covalent radii of gold sulfide and silver are similar, and the two will form a solid solution. Brief ...

2016-1-1 · Gold in refractory sulfide ores occurs as fine inclusions or in solid solution typically within pyrite, marcasite, and arsenopyrite grains. In this type of ore, because the gold is encapsulated, the interaction with cyanide to form the soluble metal complex is inhibited (Marsden and House, 2006, La Brooy et al., 1994).

Sulfide ores, and pyrites, have caused and continue to cause difficulty in recovering the gold values from these Carlin type deposit ores. In most instances, visible gold cannot be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, a high rate of visible specs of gold can be seen under microscopic.
