| 摘 要： | 某难选金矿金平均品位4.84g/t,含砷0.51%,碳1.75%(其中有机炭1.07%).金粒度较细,主要分布在褐铁矿和粘土矿物中,其次以超显微晶隙状态赋存在黄铁矿和毒砂的晶格中,属难处理金矿石.试验先用浮选富集获得金精矿,然后对金精矿采用常压加温酸性预处理,再氰化浸出回收金,所采用的氧化剂在常压、适当加热条件下达到氧...

| Abstract: | The average gold grade of a refractory gold ore is 4.84g/t and it contains 0.51% of arsenic and1.75% of carbon(1.07% of organic carbon).The particles of gold are relatively fine,mainly distributing in the monite ore and clay minerals and secondarily occurring in the crystal lattice of pyrite and arsenopyrit in the ultramicroscopic interstitial state.Therefore,it belongs to the refractory kind of ore.This experiment first adopts flotation concentration to obtain gold concentrate,then pretreats it under the c... |
