Two Products Formular In Mineral Processing
Screening 101
Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.

Separation Efficiency
All the mineral particles of type "A", which respond uniquely to the selection forces acting in the ideal separator, report to the concentrate while all the mineral particles of type "non-A" report to the tailing. The result is two perfect products, pure "A" and pure "non-A".
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 engineering in China.
