Description
Technical field
The present invention relates to a kind of separation system of ore and sorting process, concretely relate to a kind of carbonate-type fluorite
The separation system and sorting process of mine.
Background technique
The potentiality of China's flworite resources are big, but rich ore is few, and lean ore is more, and hardly possible sorts more, and what is easily sorted lacks；Single type
Fluorite deposit is more, but reserves are few；Association type mineral deposit quantity is few altogether, but reserves are big.According to the origin cause of formation in mineral deposit and intergrowth mineral object
Difference, China's fluorite ore is broadly divided into three classes: silicate-type fluorite ore, carbonate-type-sulfate type fluorite ore, more metals are total
With type fluorite ore.At present to develop based on single type fluorite deposit, the exploitation of total association type fluorite ore is just started.Because of skill
Art is limited, is total to the synthetical recovery difficulty of association type fluorite ore greatly and serious waste of resources.Difference can be used for different fluorite ores
Ore-dressing technique and method, sorting, magnetic separation, gravity treatment and flotation get application in processing of fluorspar ores.
Carbonate-type fluorite ore is the emphasis of the following exploitation, at present mostly based on the separation method of flotation, but such mine
Object complicated component, sorts that difficulty is big, and comprehensive resource utilization rate is low.This is because there are fluorites and side's solution in carbonate-type fluorite ore
Contain identical metal cation --- calcium ion in the lattice of stone, fluorite and calcite, and the two dissolubility is similar, part
Fluorite and calcite can dissolve in the solution, and exist in the form of an ion, dissolving ion F-And CO3 2-It can be in other mineral surfaces
It reacts, mutually converts fluorite and calcite mineral surface ion, then two kinds of mineral have similar Surface Physical Chemistry

Sound is larger, so that the difficulty of the FLOTATION SEPARATION of fluorite and calcite increases.Meanwhile conventional inhibitor is higher to calcium carbonate content
Fluorite ore be difficult to realize effectively remove calcite in concentrate.
Now in terms of fluorite ore ore dressing, stage grinding, stage grading, repeatedly it is selected be fluorite main process
(as shown in Figure 1), but there is the disadvantages of structure is complicated, and occupied area is wide, energy consumption is high in the technique, and be only limitted to fluorine in fluorite ore
The extraction for changing calcium, Calcium Fluoride Content is 14.78wt% in tailing, calcium carbonate content 50.05wt%, and dioxide-containing silica is
19.61%, fluorite ore cannot be made full use of, waste of resource, pile up like a mountain for obtained a large amount of tailings, pollutes environment.Though in addition,
The floating agent of calcite separation is had conducted extensive research in right industry, also achieves many research achievements, but FLOTATION SEPARATION
And the limitation of floating agent application is still very big, not yet develops mature floatation system and technique at present, and rarely have height
Effect, stable inhibitor.Therefore, needing exploitation can be used for the novel floatation equipment and flotation work of the sorting of carbonate-type fluorite ore
Skill.
