摘　　要：为提高黄金浮选尾矿资源利用率,对浮选尾矿开展工艺矿物学、黄铁矿界面活化和回收硫试验研究。以ZJ-H02为活化剂,矿浆pH值为4.5,对黄铁矿界面活化1 h后调整矿浆pH值为6.5,异戊基钠黄药用量为350 g/t,矿浆浓度为33%,可以获得硫品位为48.32%,硫回收率为93.37%的硫精矿。In order to improve the resource utilization rate of gold flotation tailings,the process mineralogy analysis,pyrite interface activation,and sulfur recovery from flotation tailings were experimentally studied.When ZJ-H02 is used as the activator,the pH of the slurry is 4.5,slurry pH is adjusted to 6.5 after pyrite interface activation for 1 h,isoamyl sodium xanthate dosage is 350 g/t,the slurry concentration is adjusted to 33%,the sulfur concentrate with sulfur grade of 48.32%can be obtained,and the recovery of sulfur is 93.37%.
