The Possibility Assessment of Complex Processing of Technogenic Formations Containing Zinc Sulfide

The comprehensive methodology for the zinc extraction from sulfide compounds into the oxide form with possible further reduction to metal is presented in this study. It was demonstrated in laboratory conditions during sludge treatment with Zn and ZnO obtaining. The remaining silicate products. It is proposed to recycle this material into Portland cement clinker to ensure a waste-free process.The reported study was funded by RFBR according to the research project № 18-29-24064
