Study on Technology of Floatation and Separation Copper-Zinc Ore

Jia Feng-mei

Abstract

The main minerals in the copper-zinc were chalcopyrite and sphalerite.Mineral processing was carried out by a flowsheet of selective floatation copper and regrinding and cleaning copper and reconcentration zinc from copper flotation tailings.Under the rational reagent system,copper concentrate of 18.45% Cu with a recovery of 71.54%,and zinc concentrate of 50.95% Zn with a recovery of 95.95% were obtained in closed circuit experiment.
