Chemistry of Elements

18.2. General Principles of Extraction of Metals The process of extracting the metals from their ores and refining them is calledmetallurgy. The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.
