Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nano-size grains of metallic gold.

The liberated gold is readily dissolved in conventional cyanide media ...

Sulphide Mineral Indicators For Gold – BC Gold Adventures

The main lead ore, galena is essentially lead sulfide. Galena is easy to spot since it usually displays a silvery gray color and if broken will show perfect cleavage in three directions. Galena will oxidize or “tarnish” to a dull grey when exposed to the elements. It has a specific gravity of around 7.5, which makes it fairly heavy and dense.

Recovery of Gold in Pyritic Sulfide Ores - Mine

So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores. Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This ...

Copper Mining and Extraction Sulfide Ores

changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide ; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from the roaster is called calcine. It is a solid mixture of oxides, sulfides and sulfates. One reaction that takes place is: 2CuFeS 2 (s) + 3O 2 (g) → 2FeO(s) + 2CuS(s ...

The leaching and adsorption behaviour of gold ores

Telfer oxide ore, which was not found to be preg-robbing, enhanced gold extraction was observed at low cyanide concentrations, but not at high concentrations, as the gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg-robbed. However ...
