Description
Technical field
The invention belongs to calcium mineral separation technology fields, more particularly to one kind to be used for the high calcium fluorite reverse flotation side of removing in advance
The combination medicament and its application method of Xie Shi.
Background technique
Fluorite is also known as fluorite, fluorspar powder, Fluorspar Powder, and main component is calcirm-fluoride (CaF2), Ca content 51.1%, F content
48.9%, belong to strategic mineral resource.Fluorite in nature because often comprising rare earth elements such as Ce, Th, U, Y, and show it is green,
The multiple colors such as yellow, purple, blue, black.Fluorite is the mineral that unique one kind can refine a large amount of fluorine elements, there is more superiority
Can, it is upper important raw material sources in industrial production that purposes is wide, such as: preparing hydrofluoric acid on chemical industry, extract fluorine member
Element prepares corrosive agent when for manufacturing glass and enamel for the cosolvent in making steel to remove impurity, camera eyeglass,
Also there is extensive application in the manufacture of the optical instruments such as astronomical telescope.
Fluorite belongs to calcic class mineral.In nature, fluorite often be all calcic class mineral, such as calcite, scheelite, phosphorus
The close symbiosis such as lime stone and dolomite.Floatation is separation fluorite with other calcic class mineral, and especially calcite is main
Method.But fluorite and Calcite Surface have similar calcium ion activity site, lead to the physical chemistry of two kinds of mineral surfaces
Property is extremely similar；In addition, the soluble component of two kinds of mineral enables two mineral surfaces to mutually convert again, eventually lead to
The FLOTATION SEPARATION of fluorite and calcite is extremely difficult.Currently, the separation of fluorite and calcite mainly uses under alkaline condition
It is to represent fatty acid collecting agent to carry out flotation, but need to add a large amount of waterglass and modified water glass inhibition side solution with enuatrol
Stone.However, when the content of calcite in raw ore is higher reach certain value when, i.e. high calcium fluorite can not often obtain good floating
Index is selected, or even two kinds of mineral can not be separated at all.
In order to realize the separation of fluorite and calcite, majority research, which concentrates on to find, has efficient selective to calcite
Inhibitor, such as sodium metaphosphate, dextrin, polyacrylic acid, sodium humate and tannic acid, but the flotation of high calcium fluorite is once encountered,
The inhibitory effect of these medicaments is by big heavy discount, and fluorite grade and the rate of recovery are lower, or even can not normal production.Cause
This, in order to realize the separation of fluorite and calcite in the separation of fluorite and calcite, especially high calcium fluorite, urgent need finds one kind
Efficiently it is capable of the medicament and technique of two kinds of mineral of Selective Separation.
Summary of the invention
Difficulty, fluorite concentrate grade are separated with calcite for fluorite in high calcium fluorite by the present invention and the rate of recovery is low etc. asks
Topic, provides that a kind of dosage is small, at low cost, raw material is easy to get and removes the good efficient flotation separation combination medicament of calcite effect, and beats
Broken Traditional Thinking, the method separated using fluorite and calcite reverse flotation, substantially improves the subsequent processing of fluorite.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows:
A kind of combination medicament removing calcite in advance for high calcium fluorite reverse flotation, the combination medicament include inhibitor and
