Description
Technical field
The invention belongs to technical field of beneficiation, specific kind is related to the combined capturing and collecting agent and method of a kind of betafite flotation.
Background technique
Betafite is the important uranium ore resource of the one kind in China, is distributed mainly on Shaanxi Province, Huayang valley area, Huayin City.
The type uranium ore resource reserves are huge, but uranium grade is low, and only 0.016% or so, and betafite belongs to difficult leaching uranium ore
Object, therefore directly hydrometallurgy is without economic value.The beneficiation research of betafite is less at present, consults domestic and international pertinent literature and patent
It was found that usually first pass through gravity treatment for betafite preliminary concentration, but in gravity concentrate uranium grade it is still lower, need to pass through
The further separation and concentration of flotation.At present there are mainly two types of the flotation technologies of uranium, a kind of method is inverse flotation method, by by carbonate
Mineral and sulphide flotation come out, and product is betafite product in slot, uranium in the betafite concentrate that such method obtains
Grade is still lower, and only 0.18% or so；Another method is direct flotation, selects hydroximic acid collecting agent to betafite
Direct flotation, available uranium grade is greater than 0.5% betafite, but such method betafite rate of recovery is lower, floating
To be heated when selecting, collecting agent benzyl hydroximic acid dosage it is larger, flotation higher cost.
Summary of the invention
It is an object of the invention to: current betafite flotation technology there are aiming at the problem that, invented one kind and be suitable for
The combined capturing and collecting agent of betafite realizes efficient, the economic flotation of betafite.Collecting agent methyl benzyl arsonic acid and xanthate combination make
With good to the selectivity of betafite, collecting ability is strong, and dosing is few, can obtain high-recovery, high-grade niobium titanium uranium
Subsequent uranium hydrometallurgy throughput can be greatly reduced in mine, reduce reagent consumption, achieve the purpose that save production cost.
Technical scheme is as follows: a kind of combined capturing and collecting agent of betafite flotation, and ingredient is methyl benzyl arsonic acid and fourth
Base xanthate, wherein methyl benzyl arsonic acid mass fraction accounts for 60~90%, and butyl xanthate mass fraction accounts for 10~40%.The methylbenzyl
The purity of arsenic acid and butyl xanthate is that analysis is pure.
A kind of method of betafite flotation, uses combined capturing and collecting agent described in claim 1, comprising the following steps:
(1) collecting agent solution is prepared；
Combined capturing and collecting agent described in claim 1 is added in 40~85 DEG C of hot water, compound concentration be 0.5~
15% collecting agent solution；
(2) ore grinding；
The ore grain size of betafite is milled to -0.074mm and accounts for 40~90%, obtains ore pulp；
(3) it sizes mixing；
The ore pulp of milled is put into flotation device, adjustment pulp density is 10%~50%, and sulfuric acid is added and adjusts ore pulp Ph value；
(4) flotation betafite；
In the ore pulp that step (3) obtains, prepared collecting agent solution is added, is sufficiently stirred, keeps collecting agent selective
The mineral surfaces for acting on betafite keep its hydrophobic；Foaming agent is added, is sufficiently stirred；In collecting agent solution and foaming agent and mine
After object sufficiently acts on, inflation carries out flotation to betafite, and obtained froth pulp is betafite rough concentrate, into flotation cell
50~300g/t of collecting agent is added in product again, is scanned primary；
(5) betafite rough concentrate obtained in step (4) is carried out again it is repeatedly selected, until reaching ideal flotation and referring to
Mark.
Further, in step (3), ore pulp Ph value is adjusted to 3.5~6.
Further, in step (4), the collector dosage is 150~1500g/t.
Further, in step (4), the mixing time after collecting agent solution is added is 1~10min.
Further, in step (4), the foaming agent is No. 2 oil.
Further, in step (4), the frother dosages are 25~100g/t.
Further, in step (4), the mixing time after foaming agent is added is 1~10min.
Remarkable result of the invention is: can be realized niobium using the combined capturing and collecting agent that methyl benzyl arsonic acid and butyl xanthate form
The combined capturing and collecting agent of effective flotation of brannerite, invention has selectivity good, and collecting ability is strong, low to flotation temperature requirement,
The features such as dosage is few.Gravity concentrate passes through one roughing once purging selection recleaning closed circuit technological process, the uranium in flotation concentrate
Grade can achieve 1% or more, 92% or more the rate of recovery.Concentrate yield only has 6% or so of flotation raw ore, considerably reduces
The throughput and reagent of subsequent hydrometallurgy consume, and can be effectively reduced production cost.
