Description
Technical field
The present invention relates to a kind of new methods for being enriched with high-grade lepidolite concentrate, belong to technical field of beneficiation.
Background technique
Lepidolite ore is to mention lithium and the manufacture very important raw material of lithium carbonate, supports the hair of China's New Energy Industry
Exhibition.It is largely to exist in the form of associated resources, extensive preservation is in tantalum niobium concentrate body, the tax that also has for lepidolite ore
It is stored in lithium porcelain stone.Lepidolite ore is difficult to recycle, be because lepidolite in the form of sheets, it is difficult to it is levigate.Generally want it is levigate extremely
When 0.15mm or less, -400 mesh (0.038mm) content reaches 60% or more in ore milling product, is very easy to argillization, thus after influencing
Continuous floatation process process, therefore the concentrate grade of lepidolite, all 3% or so, recovery rate in ore-dressing is generally all below 70%.
In order to improve the aeneficiation effect of lepidolite, many patents solve the problems, such as floatation process from floating agent.
Chinese patent 201710322482.6 discloses a kind of lepidolite method for floating.This method is to carry out wet type for after crushing raw ore
Steel ball ball milling.Again using lauryl amine polyoxyethylene ethereal solution as collecting agent, sulfuric acid is regulator, carries out flotation point to ore pulp after ore grinding
From obtaining grade containing Li2O is 3.17%, the lepidolite concentrate that the rate of recovery is 66.38%.Chinese patent 201310163993.X is public
It has opened a kind of Novel lepidolite flotation method, including one roughing, recleaning and secondary has scanned.It is added when flotation
Inhibitor is waterglass, dosage 1400-1900g/t, and anionic collector type is enuatrol or oxidized paraffin wax soap 731,
Dosage is 480-700g/t, and anionic collector type is lauryl amine or coco amine, and dosage is 130 ~ 160g/t.Chinese patent
201510788440.2 disclosing a kind of beneficiation inhibitor of lepidolite floatation process.Use sodium metasilicate, sodium phosphate and carboxymethyl
Beneficiation inhibitor made of cellulose compounding, the flotation lepidolite concentrate from Ta Nb tailings.The beneficiation inhibitor includes silicon
Sour sodium, sodium phosphate and carboxymethyl cellulose, their proportion are 10 ~ 40:10 ~ 40:80 ~ 20.Collecting agent is cocounut oil primary amine, with salt
After acid is with the ratio mixing of mass ratio 1:1-1:5, the aqueous solution of amine mass fraction 0.5%-5% is configured to as floating agent, is added
Enter beneficiation inhibitor, dosage 50-1000g/t.Ta Nb tailings slurry solid content is 20%-30%, the pH value 5- of ore pulp when flotation
Sodium carbonate is used in 9, pH adjustings.
Even if above-mentioned patent continues to optimize flotation process and System of Flotation Reagent, lepidolite flotation recovery rate is still dashed forward
70% or more is not broken, lepidolite concentrate grade is also difficult to reach 3.5% or more.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new method for being enriched with high-grade lepidolite concentrate, send out
It on the basis of bright inhibitor, is adjusted by floatation process, realizes the enrichment method of high-grade lepidolite, while realizing lithium cloud
Female rate of recovery is up to 80% or more.
The present invention is realized by following proposal: a kind of new method being enriched with high-grade lepidolite concentrate, according to following step
