摘要
系统地试验了四类化合物对尾矿中金的捕收性能，通过浮选试验，找出了从尾矿中提取金的最佳捕收剂－次乙基二甲基二硫代氨基甲酸酯．它可将尾矿中金由５ｇ／ｔ提高到２２５０ｇ／ｔ以上，富集比高达４５０．为工业开发应用打通了道路，也为我国资源充分利用的研究提供了一条可行性方案。
A systematic test of collecting gold from flotation tailings was carried out with four types of chemicals. It is found by flotation tests that ethylene bis (dimethyldithiocarbamate) is the best coll ection reagent which can beneficiate gold from about 5g/t Au of tailings to obtain 2250g/t An of aurine, i. e. the enrichment ratio is as high as 450 times. Gold could be successfully extracted from waste ores by flotation-extraction method. This method can be widely applied in industry, and supply an approach for sufficiently mineral resources in our country.
