Comprehensive Recovery

The study aims to comprehensive recovery of Cu, Mo, Co and Fe from copper polymetallic sulphide ore in Sichuan province, China. In the light of the minerals characteristics, a united flow sheet, i.e., flotation-magnetic separation with new powerful flotation reagents were used to effectively recovery copper together with the associated valuable metals (Mo, Co and Fe) from the ore. The result of the closed circuit experiment shows that a copper recovery of 93.38% with a concentrate grade of 21.25%, Mo recovery of 45.72% with a concentrate grade of 45.78%, Co recovery of 46.42% with a concentrate grade of 0.46% and Fe recovery of 38.26% with a concentrate grade of 63.73% were achieved from the ore.

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%.
