Flotation of Low-Grade DongChuan Copper Oxide Ores with Xanthate and Hydroxamate Collectors

Abstract:

A hydroxamate collector AM28 is used in conjunction with Potassium Amyl Xanthate (PAX) to allow the flotation of the low-grade copper oxide ores from DongChuan Mine. A series of batch laboratory scale flotation tests are conducted for oxide copper minerals to establish the flotation response and the suitability of the collectors. From the rougher flotation tests performed, the highest copper recovery obtained is 78.9% at a concentrate grade of 2.5% using AM28 dosage of 740g/t and PAX dosage of 20g/t. With one stage of cleaning, the obtained copper grade increases to 9.6% with the copper recovery at 64.9%.
