从某低品位金钼粗精矿中浸出金、钼试验研究

摘要

研究了从某金钼粗精矿中浸出金和钼，考察了氧化浸出、加压氧浸和焙烧浸出对金、钼浸出率的影响，确定了氧化焙烧-碱浸钼-浸钼渣氰化浸出金的工艺流程。最佳条件下，钼浸出率大于90％，金浸出率大于95％。%Leaching of molybdenum and gold from a low grade rough gold-molybdenum concentrate were researched .The influence of oxide leaching ,pressure oxide leaching and roasting leaching on leaching of gold and molybdenum were examined .The process for the rough concentrate was determined .Under optimal conditions ,the leaching of molybdenum and gold are over 90% and 95% , respectively .
