Fluorite ore gravity separation process and fluorite waste gravity separation process

Abstract

The invention discloses a fluorite ore reselection process and a fluorite waste reselection process. The fluorite ore reselection process comprises the steps of: 1) primary crushing classification of fluorite ores; 2) primary cleaning of a flushing screen; 3) sorting by a fluorite sorting machine; 4) obtaining of finished fluorite ores through separation by a first suspension recovery screen, and obtaining of waste reselected fluorite ores through separation by a second suspension recovery screen; 5) purification of suspension by a primary suspension recovery machine; 6) secondary crushing classification of the waste reselected fluorite ores; 7) secondary cleaning by the flushing screen; 8) sorting by a fluorite particle reselection cyclone; 9) obtaining of fluorite flotation process raw materials through separation by a third suspension recovery screen; and obtaining of waste ores through separation by a fourth suspension recovery screen; and 10) purification of the suspension by a secondary suspension recovery machine. The process can replace manual hand sorting process, reduces the labor intensity, liberates labors, increases the fluorite resource recycling rate and the water and suspension recycling rate, increases the waste ratio, and largely reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of fluorite ore beneficiation and treatment technology, in particular to a fluorite ore gravity separation process and a fluorite waste gravity separation process. Background technique [0002] At present, fluorite enterprises want to obtain fluorite lump ore (particle ore), and it is known to adopt manual hand-selection process. The manual hand-selection process is to crush the fluorite ore to a certain particle size (less than 10mm), wash the broken ore, and then manually select and wash out fluorite lump mineral products of different grades according to the color difference of the fluorite ore. The grade of fluorite raw ore after mining will drop due to the extraction of rich ore, which will increase the difficulty and cost of the flotation process. [0003] Due to the manual hand-selection process, the grading and sorting of the ore is carried out by relying entirely on the experience of the workers, an...

The manual hand-selection process is to crush the fluorite ore to a certain particle size (less than 10mm), wash the broken ore, and then manually select and wash out fluorite lump mineral products of different grades according to the color difference of the fluorite ore. The grade of fluorite raw ore after mining will drop due to the extraction of rich ore, which will increase the difficulty and cost of the flotation process

[0003] Due to the manual hand-selection process, the grading and sorting of the ore is carried out by relying entirely on the experience of the workers, and the ore is judged by the naked eye. High, it is difficult to carry out large-scale production; on the other hand, to reduce the difficulty of the flotation process and reduce the production cost of the flotation process, it is necessary to discard (tail) enrichment of fluorite raw ore
