摘要
本文报道了湖南江永锌精矿采用常压酸氧化法进行直接浸取的研究结果．以硝酸为催化剂、空气为氧化剂，用硫酸直接浸取，一级浸取的锌浸出率可高达９３．０２％．当锌浸出率为８３．３１％时，硫磺产率可达７５．２０％．因此，可以用硫酸加少量硝酸作浸取剂，在常压下直接浸取江永锌精矿．
The conditions of air oxidative leaching of the ZnS concentrate from Jiangyong,Hunan provillce,in acidic solution under atmospheric pressure were studied to detect the yields of elemental sulphur and Zinc products.The rate,or percentage,of Zinc leached from ZnS concentrate into solution is high as 93.02% by only one step of leaching.The yield of Sulphur may be high as 75.20% When the rate of zine leached out is 83.31%.It is,ofcourse,possible to process Jiangyong ZnS concentrate by this leaching process.
