Innovations: Introduction to Copper: Mining & Extraction
WebThe copper metal can be extracted by electrolysis or by a displacement reaction using iron. These methods allow for economical extraction of metals from the metal compounds. Also, they do not involve digging, transporting or disposing of … WebThe barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts. WebCopper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. … red hot chili peppers youku
