摘要
Abstract
The flotation behavior of chalcopyrite and Cu - aqtivitatded marmatite with O - isopropyl - N - ethyl thionocarbamate (Z - 200) and the effect of sodium hexametaphosphate on their float-ability were studied by single mineral tests. The results show that the selective separation of chalcopyrite from Cu - activitatded marmatite could be achieved at the pH value range of 8 -10 when using O - isopropyl - N - ethyl thionocarbamate as collector and sodium hexametaphosphate as depressant. The results of the real ore tests shows that the combination of sodium hexametaphosphate and zinc sulfate can depress zinc minerals effectively and outputs a good result in separating zinc from copper minerals, but with some problems which need further research and optimization.关键词
