Obtaining Zn2+ from sphalerite concentrate

Valorization of zinc from polymetallic ores and concentrates is a very important branch in the metallurgical industry. Zinc is mostly extracted by hydrometallurgical methods. Leaching is most often done with the help of strong oxidizing agents, which can have a harmful effect on the environment.

The collectorless flotation of sphalerite

2014
The flotation of sphalerite has been demonstrated without the use of collectors. The effect of redox potential, pH, and copper-activation have been investigated in tests using samples of pure mineral. It has been found that in general, collectorless flotation of sphalerite can be accomplished at potentials greater than -200 mV, SHE, and is more readily
