50.5 EXTRACTION OF METALS METALLURGY Chemistry

50.5 EXTRACTION OF METALS METALLURGY. Therefore, metals are generally extracted by subjecting their ores to reduction by chemical methods or by electrolytic methods. The process of extracting pure metal from its ore is known as metallurgy. . Since, the nature of the ore and also the properties of different metals are different, therefore

Extractive Metallurgy Introduction to Chemistry

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores (leaching).
