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.
