occurance and extraction of metals from their ores」

2012-7-8  The extraction of metals from ores is what allows us to use the minerals in the ground! Ores are very different from the finished metals that we see in buildings and bridges. They consist of the desired metal compound and the impurities and earthly substances called gangue. The extraction of metals and their isolation occurs over a few major steps.
