Abstract
The invention discloses the beneficiation method of a kind of lithium Ore.Reclaiming, according to present stage China, some problems that the ore-dressing technique of lithium exists from complicated pegmatite is containing lithium Ore, develop " spodumene and lepidolite bulk flotation " technique, with BTA for helping collecting agent, tall oil is collecting agent.The technique of present invention process and present stage conventional flotation complexity pegmatite " the first flotation lepidolite, select spodumene after desliming again " containing the employing of lithium Ore is compared, and has technique simple, and processing cost is low, the strong adaptability to raw ore, and technique more stablizes the advantages such as controlled.A kind of more efficient technique is provided for containing recovery lithium resource in lithium Ore from complicated pegmatite.
Description
Technical field
Patent of the present invention belongs to mineral manufacture field, is specifically related to the Raw material processing field containing lithium Ore.
Background technology
The present stage main method of China's smelting process of extracting lithium compound from lithium concentrate is lime method, and the lithium concentrate containing spodumene and lepidolite can use lime method to smelt simultaneously.
China's lithium ore resource is many based on common association pegmatite deposit, multiple containing lithium minerals containing spodumene, lepidolite and zinnwaldite etc. in most Ores, belongs to complicated intractable pegmatite lithium deposite.Owing to the various floatabilities containing lithium minerals itself such as the lepidolite in complicated pegmatite lithium Ore and spodumene differ greatly, and the poor spodumene of floatability is highly susceptible in ore pulp the foreign ion (Al such as soluble-salt3+、Fe3+Deng) suppression, the most existing ore-dressing technique can not be single containing lithium concentrate by sorting out containing lithium minerals in Ore, can only sort out lepidolite and two kinds of concentrate products of spodumene respectively, and need desliming before the flotation of spodumene.This not only causes the loaded down with trivial details instability with sorting index of complexity of lithium ore beneficiation technique, also add the total energy consumption in recourse processing process.
Summary of the invention
Present invention seek to address that existing complexity containing the loaded down with trivial details problem of ore-dressing technique of lithium ore resource, output be suitable for that subsequent smelting processes containing lithium bulk concentrate, reduce the energy consumption in the lithium resource course of processing.
For achieving the above object, invent the beneficiation method of a kind of lithium Ore, particularly as follows:
1, by complexity lithium ore reduction, levigate；
2, the ore pulp after levigate is added in agitator NaOH and stirs scouring；
3, step 2 stirs the dehydration of the slurry concentrating after scouring, and the ore pulp after dehydration adds clear water slurrying again；
4, step 3 brand-new ore pulp carrying out lithium minerals bulk flotation operation, use BTA for helping collecting agent in the basic conditions, tall oil is collecting agent, and flotation flowsheet is that one roughing secondary scans triple cleaning, and flotation obtains lithium concentrate and mine tailing.
Further illustrate: in step 1, mog accounts for 70%～85% for-0.074mm content.
It is 11～13 that step 2 adds the slurry pH of NaOH stirring scouring, and pulp density is 30%～40%, and the mechanical agitation scouring time is 30 min～60min.
In step 3, the aqueous alkali of abjection can return to step 2 stirring after treatment and cleans operation, and concentrating underflow density is 55%～60%, and the pulp density adding clear water slurrying again is 30%～40%, and pH value is 9～10.
One roughing operation described in step 4 is stirring 3～5min after the BTA of interpolation 100g/t～500g/t and the tall oil of 100g/t～300g/t, carries out roughly selecting operation, and flotation time is 4～10min；Scanning operation for the first time, its characteristic is: stirring 2～5min after adding the tall oil of 80g/t～100g/t, flotation time is 2～6min；Second time scans operation, and its characteristic is: stirring 2min after adding the tall oil of 40g/t～60g/t, flotation time is 2～5min；Triple cleaning operation, its characteristic is: add 200g/t～400g/t, 100g/t～200g/t, the Na of 50g/t～100g/t successively2SiO3, flotation time is 3～8min.
Ore pulp adds alkali and stirs the purpose of scouring and be: one is that complicated pegmatite Ore Han lithium can produce some impurity interfering ion (Al in grinding process3+、Fe3+Deng), the poor spodumene of floatability is highly susceptible to the suppression of these foreign ions；Two is due to reasons such as Ore air slaking, can produce some particulate sludges in grinding process, and absorption is at spodumene mineral surfaces, by adding alkali and stirring scouring, can effectively clean the sludge of spodumene mineral surfaces absorption.
The lay equal stress on purpose of new slurrying of thickening is: one is the current potential (pH value) changing ore pulp system, effectively prevent the absorption again on lithium minerals surface of the particulate sludge；Two is the interference that can effectively eliminate foreign ion to follow-up lithium minerals flotation.
Roughing flotation adds the purpose of BTA and is: one is that first the fresh lithium minerals surface after can making scouring is combined with collecting agent, prevents lithium minerals and other foreign ion effects；Two is the combination accelerating to strengthen fatty acid sodium salt with lithium minerals, plays the effect of auxiliary collecting lithium minerals.
Flotation is added the purpose of tall oil and is: the mixing acids such as resinic acid that tall oil contains and higher fatty acids occurs hydrolysis in the alkaline ore pulp containing NaOH, generate a series of fatty acid sodium salt effective to lithium minerals collecting, the fatty acid sodium salt of different alkyl is respectively acting on different types of lithium minerals surface, it is achieved thereby that the effective flotation to mixing lithium minerals is reclaimed.
Accompanying drawing illustrates:
Fig. 1 is the mineral processing circuit figure of the present invention.
