Possible ways of technogenic formations processing with zinc extraction from sulphide compounds

Abstract

Extraction of zinc from sulphide forms by pyrometallurgical methods is difficult due to the high energy of the "zinc-sulfur" bond. Theoretically justified and experimentally confirmed the possible methods of extracting zinc from such compounds by changing of raw material phase composition. The zinc oxide obtained by this way has high purity and does not require additional purification by hydrochemical methods. © The Authors, published by EDP Sciences.
