Description
Technical field
The present invention relates to a kind of cassiterite polymetallic sulphide ore beneficiation method, belong to technical field of beneficiation.
Background technology
It is cassiterite sulfide type mineral deposit that China's Tin Resources enriches main deposit type, and such as Geju City, big factory cassiterite etc., distributed areas are wide, is mainly distributed on Yunnan, Guangxi, Guangdong, Hunan etc. and economizes. Association component is many, and comprehensive utilization value is big. Cassiterite (SnO2) be main reclaim containing tin mineral. China more than 3/4 tin metal derives from cassiterite, cassiterite reserves about 3,840,000 tons, occupies first place in the world. Including cassiterite, teallite, stannite, brightness antimony nigerite, varlamoffite etc. containing tin mineral, but cassiterite is tin metal uniquely available mineral, in general other tin mineral there is no economic worth. Along with the reduction day by day of cassiterite head grade, making the intractability of Fine cassiterite strengthen, and cassiterite is crisp, in grinding process, easy mistake is pulverized, and forms thin mud, thus causing that the response rate of cassiterite reduces, reagent cost increases. The key being developed into flotation for recovery of fine level cassiterite of new collector. In tin-lead soldering technique, the research of tin-lead soldering agent, based on collecting agent, regulator (inhibitor) is auxiliary. The tin-lead soldering collecting agent of current industrial use mainly has arsenic acid class (benzyl arsenic acid), fatty acid (oleic-acid), alkyl hydroximic acid, alkyl sulfosuccinate, p-toluene sulphonic acid, phosphonic acid based etc. Appearance (typical example is toluene arsonic acid and styryl phosphonic acid) since arsenic acid class and phosphonic acid based tin-lead soldering agent, flotation efficiency is made to be significantly improved the recovery to coarse grain cassiterite, conventional is gravity separation method at present, increase along with the exploitation time, rich ore is petered out, on the one hand, the embedding cloth feature of cassiterite Ore is increasingly sophisticated, inevitably has valence component (such as sulphide ore etc.) to be placed on position of equal importance by reclaiming other in the recovery of cassiterite; On the other hand, owing to cassiterite is crisp, frangible, it is too thin that this allows for running into the unvanquishable contradiction granularity of gravity treatment institute in the technique reclaiming cassiterite.
Ore dressing for cassiterite polymetallic sulphide ore, generally first sulfide mineral is deviate from by the method for flotation, the method of cassiterite enrichment recycling gravity treatment is reclaimed cassiterite by the method that the Ore having sloughed sulfide mineral adopts flotation again, how to control a difficult problem for process chats stone grinding particle size, namely when sulfide mineral adopts the method elimination of flotation, require that Ore grinding particle size is thinner, so just be conducive to the flotation of sulfide mineral, if but Ore grinding particle size is thinner, make cassiterite over grind, be unfavorable for that cassiterite gravity separation technology reclaims.
Through retrieval, find some open source literatures about cassiterite polymetallic sulphide ore ore grinding, flotation:
1, name is called the beneficiation method of cassiterite Ore, the patent No. is CN200410045027.9, this technology is to fine fraction part flotation less than 0.039mm after ore pulp classification, flotation adopts roughly selects the flow process of once purging selection triple cleaning for twice and is simultaneously introduced medicament tributyl phosphate at ore grinding, Ore does not need predictive desliming, the method of direct flotation reclaims stannum at the cassiterite-quartz type Ore processing stannum grade 0.6%��2%, obtains grade more than 26% response rate 80% Tin concentrate.
2, name is called desulphurizing cassiterite polymetallic sulphide ore tailing by flotation step by step method, the patent No. is CN201010102296, disclose the difference utilizing sulphide ore floatability, the method that substep carries out flotation removing sulphide ore, first the good sulphide ore of floatability is carried out flotation, then flotation tailing is carried out intensified Daqu by shaking table enrichment for adding inhibitor waterglass, activator sodium sulfide and trapping agent amyl group xanthate in cassiterite sulphide ore mixed crude concentrate.
Above two method will simultaneously by the sulphide ore of multistep gravity treatment and the method for flotation and Tin concentrate.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, the present invention provides a kind of cassiterite polymetallic sulphide ore beneficiation method. The method enables to valuable mineral by selective milling-method for floating and is effectively recycled, and significantly simplifies the flow process selecting stannum, has good economic benefit. Solving in cassiterite polymetallic sulphide ore ore dressing process tradition reselecting method and cassiterite sorts efficiency is low, water utilization rate is low, cassiterite is enriched to certain taste and is conducive to subsequent reselection technique to reclaim cassiterite, the present invention is achieved through the following technical solutions.
A kind of cassiterite polymetallic sulphide ore beneficiation method, it specifically comprises the following steps that
(1) putting in ore mill by cassiterite polymetallic sulphide ore, ore grinding to-200 orders reach the ore materials of 85%;
(2) ore materials through step (1) being carried out a flotation and obtain sulphide ore and remaining ore pulp, the flotation reagent added in floatation process is butyl xanthate 500 g ton cassiterite polymetallic sulphide ore, foaming agent terpenic oil 20 g ton cassiterite polymetallic sulphide ore;
(3) Tin concentrate and mine tailing are obtained after remaining ore pulp being carried out one roughing, once purging selection, recleaning flotation.
Described step (1) ore milling concentration is 65%, and it is 7��8 that the acid-base value of ore grinding system controls pH.
Described step (1) ore mill is wet ball mill.
In described step (3) floatation process, one roughing, once purging selection, recleaning add the waterglass of 190��220 g ton cassiterite polymetallic sulphide ores and the straw cellulose of 50��70 g ton cassiterite polymetallic sulphide ores as inhibitor every time, the benzyl arsenic acid of mass ratio 1:1 and N-nitroso-group-B-phenyl hydroxylammonium are as collecting agent, collecting agent addition is 1000 g ton cassiterite polymetallic sulphide ores, and the terpenic oil of 20 g ton cassiterite polymetallic sulphide ores is as foaming agent.
The invention has the beneficial effects as follows: by putting in flotation cell after cassiterite polymetallic sulphide ore is carried out ore grinding, be sufficiently stirred for, by flotation by valuable mineral copper mine priority enrichment, then sort for cassiterite. Valuable mineral is reasonably recycled. Meanwhile significantly simplified the flow process of gravity treatment cassiterite by the flotation of cassiterite, there is good economic benefit. Solve in cassiterite polymetallic sulphide ore ore dressing process tradition reselecting method and cassiterite is sorted that efficiency is low, water utilization rate is low, cassiterite is enriched to certain taste and is conducive to subsequent reselection technique to reclaim sorting cassiterite by shaking table.
