  • Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

    17/03/2017· The Problem with separating Copper from Zinc by flotation. The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. The method of ore deposition is also a factor for

    The recovery of copper and cobalt from ancient copper slags from the Küre region of Turkey was investigated. A fayalitic-type of ancient copper slag containing 1.24% Cu, 0.53% Co and 53.16% Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.
