Magnesite (magnesium) Flotation Process

The following two methods is the designed magnesite (magnesium) flotation process by us. High grade magnesite (magnesium) ore flotation process: the grinding fine ore will feed into agitation tank, and meshed with flotation reagent. Reverse flotation will get the concentrate ore pulp. Then pulp will transport into thickener and reduce the water.

Magnesite Mining, Magnesite Flotation Process Xinhai

[Process Introduction] Magnesite Flotation Process- Crushing and Grinding Process. Crushing: raw ore (less than 200mm) go through the two stages one close circuit process, which include jaw crusher and vibrating screen.And then broken to 10~0mm. Grinding: the crushed ore will closed-circuit grinding, in which ore will be ground to -200mm 70%, then into flotation process;

Flotation Cell an overview ScienceDirect Topics

In Mineral Processing Design and Operations (Second Edition), 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.
