Beneficiation - an overview ScienceDirect Topics

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.
