3tph gravity flotation of gold ores

2016-1-1  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.

Optimisation of gold recovery by selective gold

This may be an alternative treatment route for gold room applications where fine gold losses can occur when treating gravity concentrates with pyrite and copper sulphides present. Floating gold from the sulphides could produce a directly smeltable product. Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11.

Gold Flotation qxdali

Flotation is one of the most widely used methods to process gold ores, especially suitable for sulfide gold ores with high reproducibility. This method is suitable for processing gold-bearing sulfide ores with fine gold particles and good flotability. In the flotation process, sulfide ores are enriched in sulfide concentrates as gold carriers.
