Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

Developing a Bulk Circuit Suitable for Chalcopyrite Pyrite

Developing a Bulk Circuit Suitable for Chalcopyrite Pyrite

A simpler flotation circuit with lower operating and capital costs for treatment of such copper gold pyrite ores with an elevated pyrite head assay was sought in this work. After characterizing the ore, the objective was to apply bulk rougher flotation of both the copper minerals and pyrite for the copper gold pyrite ore at natural pH.

Consequently, gold flotation recovery requires a focus on floating the associated base metals (predominantly lead, copper) and often pyrite minerals. While lime is often used in base sulphide mineral flotation, because excess lime also tends to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold

Depression of pyrite in the flotation of copper Trove

The relatively strong flotation of iron sulphides is caused by their copper activation from copper species dissolved from copper minerals present in the ore. In this study, several methods were used to reduce copper activation of pyrite during grinding or to minimise its effect on the flotation of pyrite at pH 9.0.

2. pH is important for pyrite flotation. Normally, pyrite can float well at acid conditions without adding any activator. However, if you want to float the pyrite at alkaline conditions, you need to add Cu2+ as activator, because pyrite can be depressed at alkaline conditions. 3.
