Extraction Of Metals Methods Of Extraction Of Metals

The extraction of metals from ores is what allows us to use the minerals in the ground the ores are very different from the finished metals that we see in buildings and bridges.Ores consist of the desired metal compound and the impurities and earthly substances called gangue.The extraction of metals and its isolation occurs over a few major.
