Galena Lead Ore Beneficiation and Upgrading Plant
The composition of galena is PbS with its good floatability and specific gravity of 7.4-7.6. So the beneficiation of galena lead ore is floatation separation and gravity separation. Floatation separation makes use of its floatability to get high grade galena concentrate. Floatation beneficiation processing can help to get high enrichment efficiency, but it requires much about the operator with ...

Galena concentrate had similar dominant fracture breakage along the grain boundaries at the initial breakage stage, at both high and low agitator speeds. Quartz, on the other hand, breaks via fracture at low agitator speed while abrading at higher speed. The breakage mechanism of selected minerals can be controlled by manipulating mill operation.
