Beneficiation

K.A. Natarajan, in Biotechnology of Metals, 2018 Bacterial Depyritization of Sphalerite and Galena. Beneficiation of complex base metal sulfide ores is based on selective production of individual clean concentrates of copper, zinc, and lead. Sphalerite flotation through copper activation becomes complicated when other minerals such as pyrite can get inadvertently activated.

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 ...
