Crushing Mineral Processing

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.

Flotation Used for Separate Fine Minerals

01: Add dispersing agent in pulp to avoid micro-grained minerals cohesion and keep them in a suitable separated state. We could use water glass, sodium polyphosphate and sodium hydroxide as dispersing agent. 02: Flotation of different mineral surfaces is improved by using low concentration pulp.
