摘要:
针对含金锑矿回收利用难,提出了一种还原固硫焙烧—选冶联合提取工艺,分别以ZnO和碳粉为固硫剂和还原剂进行硫化锑还原固硫焙烧,直接产出富集了金的金属锑,同时产出硫化锌,再选别分离得到粗锑粉和硫化锌精矿。主要研究了焙烧过程固硫机理,证明整个还原固硫焙烧分2步进行:在800 ℃之前,主要发生Sb2S3与ZnO的交互反应,生成Sb2O3;当温度高于800 ℃时,Sb2O3才会被大量还原成金属锑。固硫反应和还原反应均较为充分,在1 000 ℃条件下固硫率和金属锑生成率分别为98.96%和92.99%,且金属锑和硫化锌颗粒无包裹。金锑矿焙烧后通过重选—浮选获得了90.57%的锑直收率,其中锑品位为92.06%,金含量达134×10-6,金回收率为87.82%,同时硫化锌精矿品位和固硫率分别达79.10%和94.35%,验证了工艺的可行性,新工艺具有低温、低碳及清洁环保的优点。
