Ores and Minerals - Introduction, Extraction ...

Before applying all these methods of extraction of metals according to their reactivity, concentration of ores is done. Ores are found in nature with many impurities such as rock particles, sand and other impurities. These impurities in an ore are called matrix or gauge. The removal of matrix or gauge from the ore is called concentration ore.

Rock Crushing methods and How to recover gold from Ores
