使用选冶联合流程时,可从难选的含锡多金属矿石中提高锡的回收率和矿物原料综合利用的程度。矿石的特点是金属矿物的连晶很细(达到0.001毫米)。根据复杂的重浮流程,大量的锡、铅和锌都随着细矿泥流失,这种细矿泥是在精矿的精选循环中中矿再磨时形成的。在合格同名精矿中回收有(%):锡54,铅61.2,锌60.3(表
The use of the combined process of metallurgy and metallurgy can increase the recovery of tin and the degree of comprehensive utilization of mineral raw materials from refractory tin-containing polymetallic ores. Ore is characterized by very fine crystals (up to 0.001 mm) of metallic minerals. Due to the complex, heavy flow, large quantities of tin, lead and zinc are lost with fine slimes that are formed during secondary grinding of the concentrate in the concentrate cycle. Recover in the same name with the same concentrate (%): tin 54, lead 61.2, zinc 60.3 (Table
