Extraction of Iron Concentration of Ore An Overview

Sep 23, 2019  The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

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).
