Sphalerite: Meanings, Properties and Powers - The Complete ...

Sphalerite is a zinc ore, and its name pertains to the Greek word that means ‘treacherous’. This is because it looks a lot like Galena, only it does not contain lead, much to the disappointment of early miners.. Sphalerite is a significant zinc ore which is usually found in hydrothermal veins.

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.
