Abstract: Salicylhydroxamic acid is a selectivity collector in flotation separation of rutile with garnet,but its collecting power is poor.In this paper,emulsified kerosene was using as collector intensifier to improve the collecting power of Salicylhydroxamic acid (SHA),in order to reduce the dosage of collector.Batch flotation tests of single mineral and artificial mixed mineral were conducted,the results indicated that the emulsifier types,the addition method of emulsified kerosene,mass ratio of emulsifier and kerosene,the concentration of emulsified kerosene can significantly affect the performance on flotation of rutile from garnet.Appropriate dosage of emulsified kerosene can significantly reduce the consumption of SHA,thereby reduce reagent cost.
