重浮联合工艺从某复杂多金属氧化矿中回收金试验研究

Experimental Study on the Gold Recovery by the Combination Process of Gravity Concentration and Flotation Technology from a Complex Polymetallic Oxidized Ore

对甘肃某多金属氧化矿进行了选矿试验研究,结果表明,采用优先重选—重选尾矿经一次粗选、两次精选、三次扫选的重浮联合工艺流程,可以获得金品位42.43 g/t的重选精矿和22.43 g/t的浮选精矿,金的综合回收率达到81.35%。同时,银和铜也得到一定程度的综合回收。

Mineral processing experiments were carried out on a complex multi-metal oxidized ore from Gansu.The results indicated that adopting the flowsheet of gravity concentration first,then through one roughing,twice cleaning and triple scavenging can get concentrates with the gravity concentrate grade of 42.43 g/t Au and flotation concentrate grade of 22.43 g/t Au,and comprehensive recovery of gold can reach 81.35%.At the same time,silver and copper also could be comprehensively recoveried during the operation.
