Description
【Technical field】The present invention relates to a kind of beneficiation inhibitor of lepidolite floatation process, is a kind of suppression specifically
The flotation of feldspar and quartz mineral processed, so as to improve the method for the lepidolite rate of recovery.
【Background technology】Feld Spar in Yichun Guimaraesite Mine is recycled for the lepidolite in tailing using the method for flotation, floating agent
Li in the lepidolite concentrate product obtained for cocounut oil primary amine, this method2O content is generally 3.5% or so, later use lepidolite
Concentrate carries out lithium carbonate extraction and requires lepidolite concentrate Li2O content reaches 4.5~5.0%.Because lepidolite concentrate Li2O content
Higher, the chemical agent consumption needed for thermophilic digestion process processing lepidolite concentrate will be smaller, will so reduce lithium carbonate production
The medicament integrated treatment load and environmental emission pressure of enterprise, reduce lithium carbonate manufacturing enterprise lithium carbonate production cost.
In Feld Spar in Yichun Guimaraesite Mine tailing contain about 55~60% feldspar, 15~20% quartz, apatite mineral 3~5%,
Mica mineral 10~15%, other class impurity 1~2%.Existing process is floating agent using cocounut oil primary amine, generally adds water
Glass is depressing agent, in lepidolite concentrate lithium content generally 3.5~4.2% (with Li2O is counted), lepidolite synthetical recovery
Rate is less than 70%.Such as patent CN103240185A, the inhibitor added when flotation are waterglass, dosage for 1400~
1900g/t, anionic collector are enuatrol or oxidized paraffin wax soap 731, its dosage is 480~700g/t, cation-collecting agent
Species is lauryl amine or coco amine, its dosage is 130~160g/t.By one roughing, recleaning and it is secondary scan, lithium cloud
Female concentrate rate of recovery reaches 75%~80%, in lepidolite concentrate lithium content generally more than 3.6%~4.0% (with Li2O
Meter).Floating agent described in patent CN102284373A includes foaming agent and collecting agent, wherein using cocounut oil primary amine straight for foaming agent
Addition is connect, foaming agent additive amount is 20~200g/t, uses ether alcohol, terebinthine composite drug as collecting agent, collecting agent addition
Measure as 50~300g/t, added by 2%~50% solution concentration of mass ratio, the lepidolite concentrate rate of recovery reaches 80%
More than, in lepidolite concentrate lithium content more than 4.0% (with Li2O is counted).Patent ZL201110025088.9 discloses a kind of tantalum
The method of niobium tailing FLOTATION SEPARATION lepidolite concentrate, in the range of pH5~9, uses kiber alkyl amine salt, alkyl mixed alcohol and alkali gold
Belong to the floating agent that salt compounding forms, lepidolite concentrate is floatingly selected from Ta Nb tailings.The kiber alkyl amine salt is by carbochain
One or more in the kiber alkyl amine of length 8~18, with hydrochloric acid or acetic acid reaction generation kiber alkyl amine salt；Alkyl mixed alcohol is
Refer to the alkyl mixed alcohol of carbon chain lengths 2~12, alkali metal salt refers to sodium chloride and/or potassium chloride.The method of the invention is by alkane
Base primary amine salt, alkyl mixed alcohol, alkali metal salt are configured to the aqueous solution conduct of amine mass fraction 0.5%~5% by a certain percentage
Floating agent, in lepidolite concentrate lithium content more than 4.2% (with Li2O is counted).
【The content of the invention】
The purpose of the invention is to improve the deficiencies in the prior art, beneficiation inhibitor is added in lepidolite floatation process,
Reach the higher rate of recovery and selectivity during FLOTATION SEPARATION lepidolite from Ta Nb tailings.
A kind of beneficiation inhibitor of lepidolite floatation process described in this patent, is made of following mass ratioes：Sodium metasilicate, phosphorus
Sour sodium and carboxymethyl cellulose, their proportioning are 10~40：10~40：80~20, its dosage is 50-1000g/t.Specific mistake
