Typically, mill tailings range from sand to silt-clay in particle size (40 to 90 percent passing a 0.075 mm (No. 200) sieve), depending on the degree of processing needed to recover the ore. The basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface stone properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is …
