Abstract

In this study were investigated the surface morphology, chemical content and phase composition of two sorts of copper cakes from zinc plant of KCM-Plovdiv, Bulgaria. The aim of this research is the utilization of valuable copper from copper cakes and reduction the amounts of the specific secondary wastes from hydrometallurgy plants. The copper cake with low chlorine content was tested for leaching with diluted 12% sulphuric acid. The very first results indicate that at simple leaching the cake suspension with the mineral acid generates a substantial amount of dissolved copper sulphate. The leaching process, respectively the concentration of the copper sulphate, has the potential to be further optimized for direct formation of copper sulphate electrolytes from this specific waste product.

Keywords: copper cake, surface morphology, cuprite, sulphuric acid leaching
