Abstract
The invention relates to the technical field of mineral processing, in particular to a production method for preferably selecting lepidolite from tantalum and niobium ores. The technological process comprises crushing, ore grinding, desliming and floation, the flotation concentrate is filtered by a high-frequency vibrating screen to obtain lepidolite concentrate and secondary lepidolite concentrate, the flotation tailings are re-elected to obtain tantalum and niobium concentrate, and the re-elected tailings are magnetically separated to obtain feldspar concentrate. The comprehensive recovery rate of lepidolite in the tantalum and niobium ores is greater than 70%, so that the economic efficiency of tantalum and niobium ores is greatly improved. The production method provided by the invention is particularly suitable for preferably selecting the lepidolite from the low-grade tantalum and niobium ores.
Description
Technical field
The present invention relates to technique of preparing field, specifically a kind of from tantalum niobium concentrate the production method of preferred lithium mica.
Background technology
Gangue mineral in China tantalum niobium mineral deposit is that traditional tantalum niobium concentrate mineral processing circuit is referring to Fig. 1 taking feldspar, quartz, mica etc. as main silicate mineral mostly at present.Tantalum niobium concentrate ore dressing generally first adopts gravity treatment to abandon most of gangue mineral, obtains tantalum niobium rough concentrate, then adopts gravity separation technology conventionally can obtain good preenrichment effect.The later classified desliming of ore of gravity treatment tantalum niobium enters flotation operation, and with regard to flotation, lepidolite is main purpose mineral, and main gangue mineral is quartz and feldspar.Flotation after the general first gravity treatment of tantalum niobium concentrate, magnetic separation---to obtain different products.
Along with the growth of social demand, also growing to the exploitation of low-grade tantalum niobium concentrate, traditional mineral processing circuit is no longer applicable to such ore.Particularly along with the demand of lithium battery increases, lepidolite material value continues soaring, and the rate of recovery of traditional tantalum niobium concentrate ore-dressing technique lepidolite is below 50%, and grade lithium is only 1.12%, makes tantalum niobium concentrate Beneficiation be subject to restriction.Explore suitable beneficiation flowsheet, particularly improve the rate of recovery of lepidolite, become the effective way of rationally utilizing such ore to increase production and improve productivity.
Summary of the invention
It is low that object of the present invention will solve traditional tantalum niobium concentrate ore-dressing technique lepidolite rate of recovery exactly, has a strong impact on the problem of Beneficiation, provide a kind of from tantalum niobium concentrate the production method of preferred lithium mica.
Concrete scheme of the present invention is: a kind of from tantalum niobium concentrate the production method of preferred lithium mica, it is characterized in that: comprise following processing step: (1) tantalum niobium concentrate is carried out to fragmentation; (2) muck is added to water for ball milling, muck: water=65: 35, making fineness is that-200 orders account for 50% ore pulp; (3) desliming, adopts hydrocyclone, and the sludge in ore pulp is removed; (4) flotation; (5) flotation concentrate send high frequency shale shaker to screen, and must sieve product is lepidolite concentrate, and undersized product is lepidolite time concentrate; (6) flotation tailing obtains tantalum-niobium concentrate through gravity treatment; (7) gravity tailings obtains feldspar concentrate through magnetic separation.
Step described in the present invention (1) middle fragmentation is to select jaw crusher or oppositely rolling roller crusher.
Step described in the present invention (4) flotation comprises one roughing, once purging selection, primary cleaning; And in roughly selecting, add adjusting agent to adjust pH value to equal 3, in roughly selecting and scanning, adding collecting agent, dosage is that ore pulp per ton adds collecting agent 200-300g, wherein roughly selects and adds 70% collecting agent, scans and adds 30% collecting agent.
Adjusting agent described in the present invention is hydrochloric acid or nitric acid or sulfuric acid or other acids.
Collecting agent described in the present invention is amine (lauryl amine, octadecylamine etc.).
Step described in the present invention (5) medium-high frequency Vibration Screen screen distance is 0.15mm.
The present invention's tool compared with conventional art has the following advantages:
1. the present invention can be applicable to low-grade tantalum niobium concentrate and preferably choose lepidolite, and comprehensive recovery is greater than 70%, and grade lithium is greater than 4%, has greatly improved the economic benefit of ore dressing.
2. the tantalum-niobium concentrate rate of recovery improves 10%, and feldspar concentrate improves 5%, and comprehensive benefit is high, has significant economic benefit and social benefit.
3. process route uniqueness, easy operating.
