Principles of Extractive Metallurgy

Major steps in extraction of metal •Ore concentration •Ore is purified and concentrated unwanted rocks removed •Reduction to crude metal •Metal oxides to be reduced to metals resulting in a mixture of metals collected •Refining to obtain pure metal •To obtain a specific metal purify and remove unwanted metal impurities Principles of Extractive Metallurgy Extraction of metal
