The influence of pyrite content on the flotation of

In this work, a mixed model mineral system consisting of chalcopyrite (CuFeS 2) and pyrite (FeS 2) with varying pyrite content (2080 wt.%) was used to investigate the effect of pyrite on the pulp chemistry and chalcopyrite recovery. Flotation tests showed that chalcopyrite flotation rate, recovery and grade, as well as the pulp oxidation potential, decreased with increasing pyrite content whilst pyrite recovery increased.

Flotation Process Development and Assessment

Similar to chalcopyrite about half of the galena in the flotation feed is liberated. However, in contrast to chalcopyrite, only 15% of the liberated galena was recovered into the rougher concentrate. Most of the remaining liberated galena is recovered in the scavenger circuit.

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

Recommendations for Copper Zinc Separation by Flotation The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present.

The Flotation of Chalcocite, Bornite, Chalcopyrite, and

The flotation of chalcocite, bornite, chalcopyrite, and pyrite has been studied in a microflotation cell in which the potential of a bed of the mineral particles could be controlled electromechanically. The ethylxanthate induced flotation of each mineral is markedly dependent on electrochemical potential, with the recovery changing from 0 to 100 pct in potential intervals of 0.2 V.

Characterization and Flotation of Sulfur from Chalcopyrite

flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single stage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.

The separation of chalcopyrite and chalcocite from pyrite

Flotation of chalcopyrite and chalcocite. Before studying the separation of chalcopyrite and chalcocite from pyrite, the floatability of single copper minerals in the absence of pyrite was investigated.
