Concentration of Ores - GeeksforGeeks
2021-11-10 Concentration of ores is done before using all of these methods of metal extraction based on their reactivity. Many impurities, such as rock fragments, sand, and other impurities, can be present in the ore. Matrix or gauge refers to the impurities in a mineral. Concentration ore refers to the process of removing matrix or gauge from an ore.
