【摘要】 在开放体系下充氧对哈德门金矿进行富氧氰化浸出小型试验及工业实践证明，富氧氰化浸出明显地提高黄金氰化浸出速度，浸出时间缩短一半，从而处理能力提高一倍，节省基建投资４０２．７８万元，年利润增加１０３．６万元，经济效益显著。更多还原

【Abstract】 In the open system, the carbon in leaching with oxygen(CILO)was carried out for Hademen Gold Mine. It was proved from the bench scale test and the industrial production that theleaching speed of cyanidation is boasted, half time of the retention time is needed and the leachingcapacity is increased doubly. The result shows that the saving of the investment is 4.02 millionand the increment of profit is 1.036 million Riminbi per year.更多还原
