concentration mineral processing

Mineral processing - Wikipedia

Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this...
