Abstract

Abstract: Effect of butyl xanthate， butylamine aerofloat and thiamine esters used alone and in combination on flotation of low-grade nickel sulphide ore were studied. The results showed that the nickel grade of rougher concentrate was up to 3% when butyl xanthate or thiamine esters was used alone for flotation of nickel sulphide ore， but recovery was low; when butylamine aerofloat was used alone， the nickel grade of rougher concentrate was up to 2% and recovery was up to 57%. When the combination collector of butylamine aerofloat and thiamine esters was used， the flotation recovery of low-grade nickel sulphide ore could be improved effectively. Infrared spectroscopic analysis of butyl xanthate， butylamine aerofloat and thiamine esters used alone and in combination was conducted， and functional mechanism of combination collectors on flotation of nickel sulphide ore was explained.

Key words: nickel sulfide ore, flotation, collector, infrared analysis
