LIQUIDLIQUID COPPER EXTRACTION PROCESS
C. SCENARIO. from the product of an open pit mine. Crushed ore from the mine will be leached using a weak sulfuric acid solution, and you will investigate an extraction process which will produce a fairly concentrated acidic copper solution from which metallic copper can be plated out. Your group is to test the licensed process,......
CHEMGUIDE: Occurrence and extraction of copper form ...
Extraction. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites. This ore is crushed, concentrated and then heated in the presence of air. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulphide and cuprous sulphide....

William Davenport. During the early years of his academic career he spent his summers working in many of Noranda Mines Company's metallurgical plants, which led quickly to the book Extractive Metallurgy of Copper. This book has gone into five English language editions (with several s) and Chinese, Farsi and Spanish language editions. He......
Solved: In The Extraction Of Copper From An Ore By Electro ...
In the extraction of copper from an ore by electrolysis, pure copper is used for the cathode and the ore is used as the anode, both in copper (II) solution. Copper from the ore dissolves then plates onto the cathode. some impurities from the ore dissolve in the solution while others remain solid and fall to the bottom as anode sludge....
