本矿样含Cu、Ag较高、含Pb、Zn较低,铜、锌、砷矿物共生关系复杂,呈固溶状态,嵌布粒度细,次生铜含量大,闪锌矿被Cu~(2+)活化严重,属难选铜锌银多金属硫化矿。磨矿中加入Na_2S,粗选加入ZnSO_4、Na_2SO_3抑锌、砷矿物,实现了铜矿物的优先浮选。经一次粗选三次精选一次扫选获铜精矿,铜扫选尾矿经一次锌粗选三次精选一次扫选获锌精矿。银矿物富集于铜精矿中。
The ore contains Cu, Ag is higher, Pb, Zn is lower, copper, zinc, arsenic minerals symbiotic relationship is complex, solid solution state, embedded fineness, secondary copper content, sphalerite Cu ~ 2+) activation is serious, is difficult to choose copper zinc silver polymetallic sulfide ore. Grinding ore by adding Na_2S, rough election by adding ZnSO_4, Na_2SO_3 inhibition of zinc, arsenic minerals, to achieve the preferential flotation of copper minerals. After a rough selection of three times a selected sweep copper concentrate, copper scavenging tailings by a rough selection of zinc three times a sweep selected by zinc concentrate. Silver mineral enriched in copper concentrate.
