Recovery Pb, Zn and S from a Chinese Lead-Zinc Mine Beneficiation Plant Tailing

Abstract:

Detailed characterisation and recovery of galena, sphalerite, and pyrrhotite from the beneficiation plant tailing of YouXi, China, was investigated. Different characterisation techniques viz. size analysis, chemical analysis, mineral analysis by Mineral Liberation Analyser（MLA）were carried out. Based on the appreciable differences in specific gravity, floatability and magnetic susceptibility between the desired lead, zinc, sulphur minerals and the gangue minerals, the flow sheets comprising desliming, flotation and magnetic separation, was used to recover galena, sphalerite, and pyrrhotite values. A lead and zinc concentrate of Pb 16.02%, Zn 35.1% and sulphur concentrate assays 35% S and 56% Fe can be produced from the tailing.
