Description
Technical field
The present invention relates to a kind of membrane separation process method in mineral processing.
Background technology
Complicated, difficult choosing that the mineral resources of China belong to more, grade are low, the mineral products of many metals symbiosis; Add that the mineral resource development and utilization that reaches several thousand is historical; High-quality resource is close to exhaustion; Its distinguishing feature is:
lean ore many, rich ore is few.
difficult ore dressing is many, and it is few to be prone to ore dressing.In the existing mineral products of supply exploiting of China; Its complexity except that accompanying element altogether how; Quite a few mineral products also has various mineral with particulate even the symbiosis of the mutual embedding cloth of microfine state; These mineral products are difficult to the enrichment utilization in addition of traditional beneficiation method, and are quite high to the new technology dependence.
mineral intergrowth is many, and single ore deposit is few.Because the complexity of mineral intergrowth adds that its comprehensive utilization technique can not get solving for a long time, not only cause a lot of mineral intergrowths to be difficult to exploitation or the symbiosis element can't be realized reclaiming, even exploitation also makes beneficiation cost increase greatly.There is following problem in traditional beneficiation method: the floating agent dosage is excessive; The rough concentrate grade is low, the rate of recovery is not high, and operation is difficulty; The object element concentrate grade is unstable, impure height; Medicament residual in the technology is too much, has influenced concentrate deposition and filtration operation, has influenced the ordinary production in mine to a certain extent.Therefore, must develop new technology, to improve the present situation in ore dressing plant.
Traditional ore-dressing technique at present commonly used has: multiple ore-dressing techniques such as floatation process such as flotation column, cyclone sorting, thickening pond precipitate and separate and high intensity magnetic separation, these technologies often exist to the purpose mineral sort single, the conventional equipment height is higher, adaptability is strong, grade is low, the rate of recovery is not high, added amount of chemical is big, floor space is excessive and deficiency such as long flow path.Therefore, study novel, ore-dressing technique efficiently, to solving complicated, the difficult choosing of Mineral Resources in China, low, the many metals symbiosis of grade, even the symbiosis of the mutual embedding cloth of microfine state, keep sustainable development to have realistic meaning.
Summary of the invention
To the problem that prior art exists, the object of the present invention is to provide a kind of efficient ore dressing in mineral processing, improved the grade of target concentrate and the membrane separation process method of the rate of recovery.
For realizing above-mentioned purpose, a kind of membrane separation process method in mineral processing of the present invention is specially: mineral aggregate is carried out the film concentration, and then the concentrate that will obtain after will handling carries out flotation.
Further, said film concentration is for to handle mineral aggregate, to obtain required mineral aggregate concentrate through membrane concentrator.
Further, said film concentration comprises micro-filtrate membrane filtration processing, film concentration and micro-filtration processing.
Further, said mineral aggregate comprises various dissimilar mineral aggregates.
Further, the film that adopts in the said film concentration comprises various ceramic membranes, hollow-fibre membrane.
Process of the present invention has that flow process is simple, efficient is high, cost is low, be easy to advantage such as industrialization, concentrates through film and carries out the consumption that flotation helps reducing medicament again, improved the grade and the rate of recovery of target concentrate greatly.
Description of drawings
Fig. 1 is a process flow diagram of the present invention;
Fig. 2 is amount of sodium sulfide and the molybdenum recovery comparison diagram during the floatation recovery molybdenum after film concentrates.
The specific embodiment
Below, with reference to accompanying drawing, the present invention is more comprehensively explained, exemplary embodiment of the present invention has been shown in the accompanying drawing.Yet the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the present invention, and scope of the present invention is fully conveyed to those of ordinary skill in the art comprehensively with complete.
A kind of membrane separation process method in mineral processing of the present invention; Adopt membrane process craft to combine, at first carry out the film concentration process of mineral aggregate, then concentrate is carried out flotation with ore-dressing technique; Through comparing with the flotation results that concentrates without film; Can find, concentrate through film and carry out the consumption that flotation helps reducing medicament again, improve the grade and the rate of recovery of target concentrate greatly.
Technological process of the present invention and characteristics
As shown in Figure 1, be the process flow diagram of membrane separation process method of the present invention.Process characteristic of the present invention is:
concentrate after the self-control film concentrates carries out flotation and raw ore direct flotation, and the object element grade is apparently higher than the latter in the rough concentrate.
5. used here film comprises various ceramic membranes, hollow-fibre membrane.
Technology applicable object of the present invention:
The recycling of valuable metal mineral in
subparticle mineral is like the recycling of rare metals such as molybdenum, bismuth in the cyclone overflow;
The sorting of
hybrid metal mineral is used like the ore-dressing technique that the copper in the cyclone sand setting, molybdenum ore thing separate;
The recycling of nonmetallic ore in
subparticle mineral is like the recycling of sulphur in the cyclone overflow.
Case history:
During specific embodiment: the feed concentration 2.61% of membrane concentrator, and contain the copper molybdenum mixing mineral aggregate of a large amount of subparticles.Adopt treating capacity 1m
3The process equipment of/d is handled continuously.
Concentrate after membrane concentrator concentrates carries out the test of flotation molybdenum ore thing again; Contrast is without the result who concentrates direct flotation molybdenum ore thing, and test shows that the former Mo grade will can obtain rough concentrate productive rate 7.20% apparently higher than the latter; Mo grade 2.88%, the rate of recovery 62.35%.If cyclone desliming part productive rate is 30%, can improve the Mo overall recovery more than 18%, the benefit highly significant after then adopting this technology.Fig. 2 is that amount of sodium sulfide and the molybdenum recovery when film concentrates back flotation molybdenum ore thing contrasts.
and for example selects the overflow of sulphur cyclone in another certain copper mine; Have fine particles, characteristics that concentration is low equally; Be difficult to utilize conventional beneficiation method to float sulphur; And, cause the floating agent consumption excessive because mineral aggregate is fine.Through adopting process of the present invention, this mineral aggregate is handled, carry out float test again, obtained desirable ore dressing effect.
During specific embodiment: the sample thin up carries out the film concentration test to about 8%, and the concentrate after film concentrates carries out Study of flotation.
Float test is illustrated in butyl xanthate consumption 120g/t, during 2# oil consumption 25g/t, can obtain sulphur concentrate yield 18%, S grade 42.05%, the good index of the S rate of recovery 72%.
The employing membrane concentrator fully can be with selecting the overflow of sulphur cyclone from concentration 8% once concentration to 50～60%, and this concentrate can directly float sulphur, obtains the sulphur concentrate of high-grade and high-recovery.Whole technology has that flow process is simple, efficient is high, cost is low, be easy to industrialization.It is significant that subparticle is reclaimed sulphur.
