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.
