云南羊拉含铜硫铁矿精选试验研究

EXPERIMENTAL RESEARCH ON A PYRITE ORE OF YANGLA IN YUNNAN

对云南羊拉含铜硫铁矿进行精选试验,采用一粗二扫二精的浮选工艺得到硫品位33.21%,回收率95.98%的硫精矿,其中含铁48.16%、含铜1.61%、含金0.6g/t。将其用于硫酸生产,可以获得含铁品位60%以上的含铜烧渣,为铜、铁、金资源回收利用创造了条件。

In this paper,experimental study was carried on a pyrite of Yangla in Yunnan.With a circuit of once rough floatation and twice scavenging followed by twice concentrating,a final concentrate of 33.21% S grade with 95.98% recovery was achieved,in which 48.16% Fe,1.16% Cu and 0.6g/t Au.Used in sulfuric acid industry,a slag containing copper with more than 60% Fe had been obtained,which created the conditions for recycling of copper,iron and gold resource.
