摘要
研究了丁基黄药、丁胺黑药和硫胺酯单独使用与组合使用对低品位硫化镍矿浮选的影响.实验结果表明,单独使用丁基黄药和硫胺酯浮选硫化镍矿时,一次粗选镍精矿品位可达3%以上,但回收率较低;单独使用丁胺黑药时,一次粗选镍精矿品位可达2%以上,回收率最高可达57%.组合用药时,丁胺黑药与硫胺酯组合使用可以有效提高低品位硫化镍矿的浮选回收率.针对丁基黄药、丁胺黑药和硫胺酯单独使用与组合使用进行了红外光谱分析,阐述了组合药剂对硫化镍矿浮选的作用机理.
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 to57%. 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.
