Mineral Processing. Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral ...

(Horst 1985, p. 3A5). Average grinding sizes for the ore can be brought down to 1015 microns at the very most, if using long grinding periods on a product which has already passed a 200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.
