摘要
本文主要阐述的内容是:对贵州省烂泥沟金矿含砷、含碳型,呈微细粒嵌布的金矿石提金工艺的研究.这类矿石是一种难以选别的新型矿石.采用常规的提金工艺流程很难达到理想的指标,必须采取强化浮选,选出的含砷、碳金精矿,再进行氧化焙烧,焙烧后的烧渣进行氰化,金浸出率可达到85～90%.
Bearing arsenic and carbon,the gold ores from Lan-Ni-Gou Gold Mine, Guizhou province are' inlaid with microgranular gold.This kind of ore is a new type of refractory gold ore, from which, the expected gold recovery is difficult to be assured by the use of conventional technology. The intensifying flotation must be adopted and the sorted gold concentrate bearing arsenic and carbon is sent to oxidizing roast. Then, the calcined ore goes to cyaniding.By this way,the gold recovery can be up to 85-90%. This paper gives a full description on it.
