    Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery

    One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South African industrial practice. From a reagent viewpoint, charged water soluble collectors such as xanthates

    01.01.2016· Most problems in gold ore flotation are not connected with floating metallic gold. The flotation recovery of free gold (throughout the text free gold is synonymous with liberated gold) is largely affected by physical constraints such as the shape and size of the gold particles and the stability of the froth. It is a generally accepted fact that liberated gold finer than about 150 μm floats

    01.01.2016· The depression of pyrite at high pH values can be overcome by the addition of more collector, stronger collector, and copper sulfate. Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and

    In sulphidic refractory gold ores, fine gold particles may be highly disseminated and locked up in sulphide minerals such as pyrite and arsenopyrite. Hence, pre-treating processes are necessary to

    Improved recovery of a low-grade refractory gold ore

    01.07.2014· In sulfidic refractory gold ores, fine gold particles may be highly disseminated and locked up in sulfide minerals such as pyrite and arsenopyrite. All the largely unoxidized ores exhibit very low gold recoveries (typically <20%) by direct cyanidation. This suggests that the primary ore, as a whole, is highly refractory in nature and will therefore have to be processed using an appropriate refractory method.

    can influence the behaviour of gold in flotation, leaching and/or recovery processes. Electrum with a high silver content may give poor gold extraction due to tarnishing of the silver (Fleming, 1998). The presence of copper in the ore at above ±0.3% concentration may make direct cyanidation uneconomic without re-treating the Cu(CN)2 formed in leaching, through processes such as SART and
