[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 mi

example 1
[0088] (1) Analyze the tin phase of the gravity separation tailings of the ore dressing plant in Linwu County South Mining Co., Ltd., Linwu County, Hunan Province. The analysis results are shown in Table 2.
[0089] Table 2, Gravity separation tailings tin phase analysis
[0090]
[0091]
[0092] The phase analysis shows that the tin grade of gravity separation tailings is 0.72%, among which the tin minerals are mainly cassiterite, the tin content in cassiterite occupies 79.17%, the tin content in phryotinite occupies 13.89%, and the colloidal tin ore The tin content in it accounts for 6.94%. Owing to the existence of zurtzite and colloidal tin, and the total amount accounts for 20.83%, it will have an adverse effect on the recovery rate of tin flotation.
[0093] (2) Particle size analysis of tin
[0094] After sampling and chemical analysis of the gravity separation tailings, the gravity separation tailings contain 0.33% lead, 0.15% zinc and 0.68% tin. The analysis...

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...
