Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining First the ore is treated with dilute sulphuric acid This trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate The copper is then recovered by electrolysis This process is known as SX-EW (solvent extraction/electrowinning) Get price

Processing of Nickel Laterite Ores on the Rise

Traditionally nickel has been processed from sulfide ores in an approach similar to copper processing in which the ore is upgraded to concentrates and then smelted As sulfide ore resources dwindle however processing of lateritic nickel ores is becoming of greater necessity with many recognizing nickel laterite ores as the future of the nickel industry Get price

Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors As in all mining operations the ore must usually be beneficiated The processing techniques depend on the nature of the ore If the ore is primarily sulfide copper Get price

GCSE CHEMISTRY

Extraction of Metals Extraction of Copper Copper is sometimes found as native metal Copper ores include copper(II) oxide and copper(II) sulfide Copper(II) oxide can be reduced by reaction with carbon Some copper ores may contain only small amounts of copper These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable Get price
