mineral processing of galena from barite 2

Galena - an overview | ScienceDirect Topics

There are many lead minerals, but galena PbS, anglesite (PbSO4 ), and cerrusite PbCO 3 are the major ones. In water, lead can occur as Pb 2 + and [PbCO 3] 0. In neutral water, the contributions of the occurrence of forms of Pb 2 + and [PbOH] + are comparable; in alkaline water (pH > 8), Pb can complex with chlorine or sulfate.

Role of Surfactants in Mineral Processing: An Overview

Froth flotation process, which uses the difference in hydrophobicity of minerals, is employed in several industries (mineral processing and others) for fines processing. It is a process of upgradation of minerals by taking advantage of differences in physico-chemical surface properties between valuable and gangue minerals of two different minerals.
