Patent CN102284373A discloses a kind of method of flotation lepidolite technique, described floating agent comprises foaming agent and collecting agent, wherein, adopt coco amine to be that foaming agent directly adds, employing ether alcohol, terebinthine composite drug are collecting agent, add with the solution concentration that mass ratio is 2 ~ 50%, the addition of foaming agent is 20 ~ 200g/t, described collecting agent addition is 50 ~ 300g/t, and this floatation process lepidolite concentrate rate of recovery reaches more than 80%, and grade lithium reaches more than 4%.Patent CN103240185 discloses a kind of Novel lepidolite flotation method, adding waterglass during flotation is inhibitor, consumption is 1400 ~ 1900g/t, anionic collector is enuatrol or oxidized paraffin wax soap 731, consumption is 480 ~ 700g/t, and cation-collecting agent is lauryl amine or coco amine, and consumption is 130 ~ 160g/t, collecting agent addition sequence is for first adding anionic collector adds cation-collecting agent again, or anionic and cationic collectors adds simultaneously.The method combined by zwitterion carrys out sorting lepidolite, good flotation effect can be obtained, not only flotation efficiency is high, and owing to creating cooperative effect between anionic and cationic collectors, this cooperative effect is eutectoid content, charge compensation and the three kinds of coefficient results of mechanism that have complementary functions.Patent ZL201110025088.9 discloses a kind of method of Ta Nb tailings FLOTATION SEPARATION lepidolite concentrate, in the scope of pH5 ~ 9, use the floating agent that kiber alkyl amine salt, alkyl mixed alcohol and alkali metal salt are composite, from Ta Nb tailings, floatingly select lepidolite concentrate.Described kiber alkyl amine salt is by one or more in the kiber alkyl amine of carbon chain lengths 8 ~ 18, generates kiber alkyl amine salt with hydrochloric acid or acetic acid reaction; Alkyl mixed alcohol refers to the alkyl mixed alcohol of carbon chain lengths 2 ~ 12, and alkali metal salt refers to sodium chloride and/or potassium chloride.Kiber alkyl amine salt, alkyl mixed alcohol, alkali metal salt are mixed with the aqueous solution of amine mass fraction 0.5% ~ 5% as floating agent by the method for the invention by a certain percentage, in lepidolite concentrate lithium content more than 4.2% (with Li
2o counts).
[summary of the invention]
The object of the invention is to improve the deficiencies in the prior art, from Ta Nb tailings, adding dressing activator in flotation lepidolite process, to reach the higher lepidolite rate of recovery.
The dressing activator of a kind of lepidolite floatation process described in this patent, this dressing activator refers to one or more in the sulfate of copper, aluminium, lithium, carbonate and/or nitrate, flotation lepidolite concentrate from Ta Nb tailings, described dressing activator consumption is 50 ~ 100g/t.
Detailed process is: collecting agent is cocounut oil primary amine, and after mixing with the ratio of mass ratio 1:1 ~ 1:5 with hydrochloric acid, the aqueous solution being mixed with amine mass fraction 0.5% ~ 5%, as floating agent, adds dressing activator, and its consumption is 50-100g/t.During flotation, Ta Nb tailings slurry solid content is 20% ~ 30%, pH value 5 ~ 9, the pH adjustment sodium carbonate of ore pulp.
