6.5.2: Mining
Ore Processing. Once an ore has been mined, it must be processed to extract pure metal. All ore minerals are mixed with less desirable components called gangue.The process of physically separating gangue minerals from ore-bearing minerals is called concentrating.When ore is processed (typically very close to the mine), it is ground to a …
