Extraction of Metals - All About Minerals, Ores & Iron,

25/09/2019· Ore: the mineral from which the metal can be economically and conventionally extracted. Depending on the element, there are three methods of extraction of metals from ores: Pyrometallurgy; Hydrometallurgy; Electrolytic reduction; Pyrometallurgy. As the name suggests, thermal energy is used to bring about chemical changes and to obtain the desired materials. The processes in this category are,Ores and Minerals - Introduction, Extraction,,For the extraction of highly reactive metals from their ores electrolysis is used and for extraction of metals of medium reactivity calcination, roasting and reduction methods are used.
