Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the ...

Flotation separation of chalcopyrite from galena by sodium ...

In the separation of copper/lead minerals by flotation, APS can be used as the depressant of galena. The effects of APS on the recovery rates of chalcopyrite and galena at pulp pH=6.5 were determined (see Fig. 5). The results indicate that with the increase of APS concentration from 0 to 200 mg/L, the floatabilities of both minerals remain

Copper-Zinc-Lead Separation Process - hiimac

The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation ...
