concentration and dressing of the ore

Ore Dressing - Sympatec

Ore Dressing. Real-time monitoring of grain size and concentration in ore slurries. The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six ...

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.
