摘要
介绍了我国难处理金矿资源的储量、分布与常规利用现状,以及国内外利用焙烧、加压与生物氧化预处理后工业利用各种工艺技术,并就广西某金矿高砷高硫金精矿利用耐高砷细菌氧化后,与氰化提金各种条件进行试验,取得金浸出率达94.17%的理想指标。
Introduce our country's reserves, distribution and general utilization status of difficult deal gold mine resource, plus pressured by roast in the whole world and all kinds of technologies of industrial used after biosynthesis oxidation pre-dealt. According to a certain gold mine of Guangxi, via the use of bacterial oxidation (high As-resistant) of gold concentrate containing rich As and S, and testing conditions of refining gold with cyanide. We have achieved ideal lixiviation index, which reached 94.17%.
