Extraction of metals from ores is called

Aug 28, 2020

Feb 26, 2019 An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Most metals are extracted from ores found in the Earth’s crust. Ores are often metal oxides , although sulfide and carbonate ores are also common
