Description
Technical field
The invention belongs to fluorite ore ore dressing treatment process technical fields, and in particular to a kind of fluorite lump ore gravity separation technology and its
System, in particular to a kind of multi-grade fluorite lump ore obtain gravity separation technology and its system.
Background technique
Fluorite is commonly called as fluorite, and main become is calcirm-fluoride, is a kind of important metallurgical raw material and industrial chemicals, the choosing of fluorite
Mine method is divided into two kinds substantially, flotation and gravity treatment.Wherein, gravity separation technology is the difference according to mineral density or particle, by stream
The effect of body power and various mechanical forces forms the loose layering and separation condition for being suitable for, to obtain different densities or different grains
Spend the technical process of product.Gravity treatment can be divided into dense media choosing, jigging, shaking table choosing, chute choosing and centrifugation choosing etc..
But above-mentioned each gravity separation technology is once it is determined that the separating density of lump ore, is only capable of fluorite more than separating density
Lump ore is separated, and density is slightly lower in lump ore but the fluorite lump ore for low one or two grade that accords with the demands of the market does not carry out
It efficiently extracts.
Therefore, the defects of fluorite lump ore produces the unicity of grade, fluorite lump ore yield is relatively low how is solved, is this field
Urgent problem to be solved.
Summary of the invention
Therefore, the technical problem to be solved by the present invention is to the production of existing fluorite lump ore, grade is single, fluorite lump ore yield is inclined
Low, to provide, a kind of lump ore utilization rate suitable for obtaining the fluorite lump ore to meet the market requirement, fluorite ore is high, can mention
The fluorite lump ore gravity separation technology and its system of high economic efficiency of enterprise.
For this purpose, the technical solution that the application takes are as follows:
A kind of fluorite lump ore gravity separation technology, includes the following steps:
