摘要:

为实现氰化尾渣中硫的资源化、无害化利用,对某氰化尾渣回收铅锌铜后的浮选尾矿进行硫浮选回收工艺研究。在矿浆浓度为35 %、pH值为5、预处理时间为60 min、捕收剂丁基黄药用量为500 g/t和起泡剂2号油用量为30 g/t的条件下,最终可获得品位在40 %以上、回收率在80 %以上的硫精矿,实现了氰化尾渣中硫资源的高效回收,并具有良好的经济和社会效益。

Abstract:

To utilize the sulfur from cyanide tailings as resources in a harmless way,the paper researched the flotation process for sulfur recovery from the tailings produced by certain cyanide tailings flotation processes to recover lead,zinc,and copper.When the slurry concentration is 35 %,the pH value is 5,the pre-treatment time is 60 min,the collector butyl xanthate dosage is 500 g/t,and frother No.2 oil dosage is 30 g/t,the sulfur concentrates with the grade over 40 % and the recovery over 80 % are obtained,realizing effective recovery of sulfur from cyanide tailings and creating good economic and social profits.
