Cassiterite flotation agent composition

Abstract

The invention provides cassiterite flotation agent composition. The cassiterite flotation agent composition comprises a collecting agent, a combined inhibitor and an optical auxiliary collecting agent, wherein the collecting agent comprises the following ingredients in percentage by weight: 30wt%-50wt% of styryl phosphoric acid, 20wt%-30wt% of aliphatic phosphoric acid (preferably selecting C6-C8 aliphatic series), 10wt%-20wt% of alkyl sulfonated succinic acid and 10wt%-20wt% of alkyl hydroximic acid. The cassiterite flotation agent composition provided by the invention is soluble under normal temperature, non-toxic and tasteless, good in dispersibility, efficient and environment-friendly and good in return water utilizability; mineral processing index of cassiterite flotation can be increased, the agent consumption can be reduced, the agent cost is reduced, and particularly for mineral processing on fine particle cassiterite, a unique effect is obtained; the loss of intermediate products during a tin rough concentrate recycling process is avoided; the industrial application processing capacity can be up to 50-60 tonnage / day, and more preferably, the industrial application processing capacity can be up to 80 tonnage / day; when the flotation ore feeding tin grade is 0.70%-0.80%, good technical indexes of 6%-10% of tin flotation concentrate grade and 60%-70% of operation recovery rate is obtained by agents; the dosage of the agents is greatly reduced.

Description

technical field [0001] The invention relates to a medicament composition in a cassiterite flotation process and belongs to the field of ore dressing. Background technique [0002] my country is rich in tin ore resources and widely distributed. Mainly primary ore deposits, of which there are many associated components, and the comprehensive utilization value is great. Cassiterite (SnO 2 ) is the main tin-bearing mineral recovered, followed by zurtinite (or kesterite). More than 75% of tin metal comes from cassiterite. [0003] The main industrial types of cassiterite occurrence: in cassiterite-rare metal deposits, cassiterite is closely symbiotic with niobite, tantalite, and beryl; in residual slope sand tin deposits, cassiterite and iron oxide minerals Dense symbiosis; in cassiterite-sulfide deposits, cassiterite and wolframite, galena, pyrite, etc. are symbiotic, and the embedded particle size is fine. Therefore, cassiterite is difficult to dissociate from other minera...

Problems solved by technology

[0009] Hunan Institute of Nonferrous Metals used K as a collector to conduct industrial experiments in Linwu Concentrator. The concentrate grade is 3% to 5%, and the recovery rate is less than 50%. It is not suitable for the applicant's cassiterite flotation recovery.

[0010] In summary, existing flotation reagents all have problems such as high cost, environmental pollution, and low fine-grained recovery (Deng Lihong, "Tin Industrial Test Report on Recycling Tin Tailings from Yuling Polymetallic Mine in Southern Mining Industry", [R] , 201303)

Among them, fatty acid collectors can produce insoluble salts with metal ions on the mineral surface and adsorb on the mineral surface, but their selectivity is poor; Like other collectors, they have strong collection ability but poor selectivity. Arsine acid collectors are toxic and have a relatively large negative impact on the environment. Although alkylhydroxamic acid collectors have better selectivity, their collection performance is weaker, so their High consumption leads to high cost

However, laboratory-level pharmaceutical compositions, firstly, after they are scaled up to industrial applications, their consumption will increase by at least 3 times, which makes them unsuitable for industrial applications.
