Iv Methods Of Obtaining Copper From Its Ores

There are three general methods of extracting copper from its ores. The dry, wet, and electrolytic methods. The wet method is used the least of the three, and consists in placing the ores in an acid solution which dissolves the copper, which is then precipitated to the bottom of the tank by the addition of suitable precipitants.There are three general methods of extracting copper from its ores. The dry, wet, and electrolytic methods. The wet method is used the least of the three, and consists in placing the ores in an acid solution which dissolves the copper, which is then precipitated to the bottom of the tank by the addition of suitable precipitants.The chief ore of copper is copper pyrite. It yields nearly 76 of the world production of copper. Extraction from copper pyrites. Extraction of copper from copper pyrites involves the following steps. 1. Crushing and concentration. The ore is crushed andThe molten copper is poured out and allowed to cool. The sulphur dioxide escaping from the melt gets trapped in the cooler parts of the surface giving a blistery appearance for copper and hence it is called blister copper. Blister copper is further refined by poling and electrolytic method, as described in the refining of metals.Jan 15, 2020 General Methods of Extraction.
