Gravity separation method is mainly used for the production of metallurgical grade fluorspar ore, sorting in accordance with the difference in specific gravity fluorite waste rock, the specific gravity of the jig and the like layered reselection apparatus, to obtain two kinds of different specific gravities Minerals, the major ones are concentrates, and the small proportion is tailings.
The ore dressing methods of fluorite ore are mainly gravity dressing, flotation and hand selection. The hand selection method and the re-election method are mainly used for extracting coarse-grained metallurgical grade fluorite ore. The flotation method is mainly used for producing high-quality fluorite concentrate for the production of chemical grade fluorite powder ore. Here, based on the experience of fluorite ore dressing of Forre Machinery for many years, a brief introduction to the re-election of fluorite ore is made, and it is hoped that it will help the relevant people.
Since metallurgical grade fluorite ore requires coarse-grained high-grade concentrate, it is necessary to first break the fluorite and wastestone in the process of sorting, and then use the re-election method to discard the fluorite essence from the obvious The difference of waste rock, in order to obtain high-quality fluorite crystal block, can be used as metallurgical fluorite.
The flotation method can only treat fine-grained fine ore, and the obtained concentrate is also powdered fluorite ore. Therefore, it is mostly used for chemical grade fluorite powder to prepare hydrofluoric acid. The hand selection method is to sort out the high-quality fluorite essence and discard the tailings by manual sorting on a horizontal speed-adjustable belt conveyor.
The selection of fluorite ore by gravity ore is mainly carried out by the jig. The jig is selected to have a large particle size, and the selected particle size range is wide. The sorting effect on the material with poor specific gravity is remarkable. The molybdenum ore beneficiation equipment is currently the vast majority in China. The jigs used in the metallurgical grade fluorite ore production plant were all made by Fo Rui Machinery, which were all successfully completed and the customers reflected well.
Both hand-selected and gravity beneficiation can obtain coarse-grained metallurgical grade fluorite lump ore, but the hand selection method is low in efficiency and high in labor cost, so it is only used for the pre-selection of large fluorite ore, small and granular fluorite ore. Need to be sorted by re-election.
The type of fluorite ore and the size of the inlay and the nature of the ore are different. It is necessary to design the beneficiation process and equipment configuration according to the actual situation and the nature of the ore. Therefore, please contact our customers and friends for the small-scale beneficiation test. According to the experimental results, the beneficiation process and equipment configuration were customized.
