Selective Separation of Chalcopyrite from Galena Using a

Flotation tests on an industrial copper–lead bulk concentrate showed that using this depressant mixture can achieve highly efficient separation of chalcopyrite from galena at the natural pH of the pulp. Copper and lead concentrates were produced at grades of 21.88% (Cu) and 75.53% (Pb), with recoveries of 89.07% (Cu) and 98.26% (Pb).

Flotation separation of chalcopyrite from galena by

2016-1-1  Generally, two kinds of basic methods are commonly used for the separation of copper/lead minerals [2,3], such as copper depression with lead flotation and lead depression with copper flotation. Some reagents such as sodium cyanide for the depression of chalcopyrite and sodium dichromate for the depression of galena are employed [4].

2021-1-1  The main copper mineral chalcopyrite is usually associated with galena. It is difficult to separate chalcopyrite and galena efficiently due to their extremely similar floatability. The effective way to improve the flotation separation of chalcopyrite and galena lies in the development of a depressant system which has high efficiency.

Copper Lead Concentrate Separation

2015-10-1  The lead-copper concentrate is cleaned if necessary, diluted to a suitable pulp density, and treated in a conditioner with sodium cyanide in sufficient strength to depress the copper minerals, the galena remaining unaffected, and with enough soda ash to make the pulp distinctly alkaline; a pH value of 9.0-10.0 is usual. The pulp then passes to
