sulfide and oxide gold ore

Gold Ore an overview ScienceDirect Topics

These are the massive base metal sulphides with arsenical gold (i.e. the lead–zinc Olympias deposit, Greece) and arsenical gold ores without the presence of base metals. Massive, base metal arsenical gold ores are rare, and there are only a few deposits in the world. A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral.

Characterizing gold in refractory sulfide gold ores and

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. During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form.

The leaching kinetics of an oxide gold ore with iodide

2012-2-1  Iodine reactions with the sulfide and ferrous minerals of the oxide ore slowly consumed iodine within 48 h. Based on the obtained experimental data, a power law rate equation was applied to model the gold extraction kinetics in iodide/iodine solutions. The reaction was found to be first order with respect to tri-iodide concentration. Highlights
