Two Basic Processes of Ore Beneficiation Process

In the beneficiation process, there are two basic processes: First, dissociation; it crushes and grinds large ore to make a variety of useful mineral particles dissociate from ore; the second step is sorting; it elects the dissociated mineral particles according to their physical and chemical differences. In nature, the vast majority of useful minerals and gangue are close quarters in together, and often has micro-fine dissemination; if not first make a variety of minerals or ingredients separated from each other, even if they have another big difference in the nature, they can not be carried out the separation.

For example, as for the flotation of mineral particles less than 5 ~ 10μm, there can not be a good recovery for the mineral particles below 19μm. So the basic tasks of crushing and grinding concentrator are to prepare good dissociation full and crushing for sorting operations; its granularity of this material to fit on the choice of sorting. So let the useful minerals and gangue full dissociation is a prerequisite of any sorting method, and crushing and grinding purpose is to make the useful minerals and pulse stone full dissociation.

Ore mining, in addition to a small number of rich in useful minerals bonanza, the vast majority are poor ore which contains large amounts of gangue. Inappropriate choice of crushing job processes and equipment, poor production operations management, inadequate dissociation for crushed product, or serious smashing will lead to the decline of the technical and economic indicators of the entire concentrator. In total, the quality of concentrator technology indicators and economic indicators often lie in crushing and grinding, so each beneficiation workers must take seriously comminution process and equipment, as much as possible to reduce the crushing and grinding costs.
