ادامه مطلبOre 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 …
ادامه مطلبAn ore is a combination of minerals and impurities. Ore is a mineral from which the metal can be extracted conveniently and economically. All minerals are not ores, but all ores are minerals. Examples: Bauxite (Al 2 O 3.2H 2 O) is the ore of Aluminium, and copper pyrite (CuFeS 2). is an ore of copper. Gangue:
ادامه مطلبImpurities are removed prior to the extraction of metal. The process used for removal of gangue from the ore are based on the differences between physical and chemical properties of the gangue.
