1. Magnetite ore stage grinding-magnetic separation process The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.
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 ...

These two circuits can be used in secondary crushing or grinding process. Normal circuit always used in the ore after blasting. It has less fine particle size ore. However, reverse circuit always used when original ore has large amount of fine particle size ore. From above process that we can obtain Returned Feed Ratio:
Roller mill. With a roller mill, a product is compressed and reduced between two counter-rotating rotating rollers. A major advantage of this process is that the proportion of fine particles (powders or dust) remains minimal compared to other grinding principles and that a nice homogeneous grain-size distribution is achievable.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
