Like other metal and non-metal beneficiation, fluorite beneficiation must go through the processes of crushing, screening, grinding, classification, flotation, filtration and drying. The main processing equipment includes: crusher (jaw crusher, cone crusher, hammer crusher), vibrating screen, feeder, ball mill, classifier, flotation machine, thickener, filter, etc. Different equipment is selected according to the processing capacity of the concentrator, different equipment is selected according to the properties of fluorite, and different beneficiation methods are adopted. Therefore, the selection of equipment for the concentrator shall be determined according to the actual situation. Because the equipment is not selected properly, the quality of the products produced will go wrong. If the beneficiation equipment produced by different manufacturers is selected, the product quality is also different. This is the experience of Fodamon engineer who have been engaged in fluorite beneficiation for more than 20 years.
According to the mineral composition of fluorite ore, fluorite can be divided into fluorite quartz type, fluorite carbonate quartz type and fluorite barite quartz type. Fluorite quartz sulfide ore type, etc. According to the grain size of fluorite ore junction, it can be divided into: the inlaid particle size of fluorite and gangue is coarse, and the inlaid particle size of fluorite and gangue is fine.
01. Fluorite quartz inlaid coarse-grained fluorite ore.
This kind of fluorite ore is easy to separate. After one roughing, two scavenging and five cleaning, high-quality fluorite concentrate can be obtained, and the recovery rate is also high.
02. Fluorite quartz inlaid fine-grained fluorite ore.
This kind of fluorite ore is more difficult to separate than the previous one. Due to the fine inlaid particle size of fluorite and quartz, it is necessary to strengthen grinding to separate fluorite from quartz monomer. Finally, qualified fluorite concentrate can be obtained through flotation.
03. Fluorite carbonate quartz fluorite ore.
This fluorite ore is difficult to beneficiate. Because the flotation properties of fluorite and calcium carbonate are the same, it is difficult to separate fluorite and calcium carbonate by conventional beneficiation methods. Qualified fluorite concentrate can also be obtained by flotation with special beneficiation methods and special reagents. This is our experience in fluorite beneficiation for many years.
04. Fluorite barite quartz fluorite ore.
This kind of fluorite ore is also difficult to beneficiate. Because the flotation properties of fluorite and barite are the same, it is difficult to separate fluorite and barite. Qualified fluorite concentrate can also be obtained by special beneficiation methods.
