DefinitionsMineral ProcessingMaking big rocks into little rocks and separating them for money The technology of economically converting mineral bearing raw material into individual mineral constituents; the minerals remaining essentially unaltered in physical and chemical form throughout. The temperature of the system normally is less than the boiling point of water. Mineral processing is also known as mineral beneficiation, milling or concentration.Unit Operation An individual process with a specific function, which is a component or forms part of a complex process.
