Fluorite (Fluorspar) Flotation Process Plant

The sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite (fluorspar) concentrate.

Mixed flotation of fluorite (fluorspar) and barite flotation, and then separate them. In mixed flotation, obtain mixed concentrate with oleic acid as collector. Mixed concentrate separation can use positive or reverse flotation to obtain fluorite (fluorspar) concentrate.

Separation of fluorite and quartz

The fatty acid collects fluorite (fluorspar), and sodium silicate restrains quartz. The dosage of sodium silicate should be controlled properly; a small amount has activation to the fluorite, but inhibition function is not enough; excessive inhibits fluorite (fluorspar). Sometimes in order to increase the inhibitory effect of sodium silicate on quartz, some multivalent metal ions will be add.
