难浸金精矿焙烧镁盐固硫剂的研究

Study on sulphurfixing roast of refractory gold concentrate with magnesium salt as sulphurfixing agent

对高硫高砷难浸金矿石的固硫焙烧预处理进行了研究。研究结果表明：某些镁盐是较好的固硫剂。经固硫焙烧后，难浸金矿石中硫的转变效率可达到８５％，而金的浸出率为８８０６％

In this paper,the pretreatment of refractory gold ore containing high sulfur and arsenic by sulfurfixing roast is studied.It shows that some magnesiun salts are fine sulfurfixing agents.After sulfurfixing roast,the change rate of sulfur in the refractory gold ore reaches 85% and the leaching rate of gold in the refractory gold ore is 8806%.
