摘要
针对某石墨尾矿中绢云母含量为24%,造成有用矿物浪费的情况,采用硫酸为pH值调整剂、淀粉为抑制剂、十二胺和柴油为捕收剂,在pH=2.5、淀粉为200g/t、捕收剂十二胺为1000g/t以及柴油为100g/t的药剂制度下经一次粗选一次扫选四次精选的浮选工艺流程后,最终获得产率为10.21%、绢云母含量为70.41%、回收率为28.95%的绢云母精矿。
Aiming at the situation of wasting graphite tailings,in that tailings,the sericite is 24%.The sericite was recovered by using sulfuric acid as regulator,starch as depressant,dodecylamine and diesel fuel as collector.The grade of the final sericite concentrate is 70.41%,the recovery is 28.95% and the productivity is 10.21% with the flow sheet which is once rough separation,once sort separation and four times cleaning separation with the pH=2.5,the dosage of starch is 200g/t,the dodecylamine is 1000g/t and the diesel fuel is 100g/t.
