Cinnabar(HgS) is the main element of Mercury beneficiation products, its density is 8.0-8.2 t/m³, hardness is 2.0-2.5, high brittleness, bright colored, good flotation, the embedded cloth size of cinnabar is not even.

According to the features of cinnabar, its process flow as follows: crushing system is using Two sections + One closed circuit process; grinding system is using One section or Two sections grinding, re-elected and flotation alliance process, re-elect for rougher size, and cinnabar by re-elected is put into grinding flotation process. A trial should be made to improve the reliability of beneficiation process. The main equipments include Jaw Crusher, Cone Crusher, Circular Vibrating Screen, Rod Mill, Ball Mill, Spiral Classifier, Shaking Table, Flotation Machine, Thickener, Filter Machine, etc. Lipu Heavy Industry can provide a unite set of crushing and screening equipment.
