  • Metallurgic Processes Boundless 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 ).

  • Refining (metallurgy) Wikipedia

    In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and
