  • Copper Ore Beneficiation Process Prominer Shanghai

    copper ore beneficiation process. views; icon copper is an earlier metal used by humans. As early as prehistoric times, people began to excavate open-pit copper mines and use the obtained copper to make weapons, tools and other utensils.We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. mining for copper bearing ore there are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.
