In the extraction of metals some factors are taking into consideration such as the chemical composition of the compound containing the metal level of impurities and the extent of chemical reactivity of the ores or mineral constituents of these metals. Generally ores are first concentrated and then changed into oxides before extraction

The ores occur as inc sulfide also called sphalerite inc carbonate smithsonite inc silicate calimine and in compounds of manganese and iron franklinite. Zinc ore is sometimes mined in conjunction with silver or lead ores. In addition to the ore itself oil and sulfuric acid are required for the breakdown of the ores and

The rock particles sink and the lead and inc ores are skimmed off. Then the lead ore is separated from the inc ore. A chemical called a depressant is added which is soluble in water for example inc sulfate and the inc ore sinks and the lead ore is skimmed off. Later a chemical such as copperII sulfate is added and the inc ore now
