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 chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

Mineral Processing and Ore Dressing

Jun 02, 2016  A preliminary crushing to the necessary fineness is made, in some cases as coarse as 2″, and then the ore is subjected to a separation through a heavy mineral suspension. The concentrated values are then further treated by finer grinding, flotation, or whatever indicated treatment is required to make a finished product.

CHAPTER 1 MINERAL DRESSING - Webs

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.
