Based on the analysis of the properties of the copper ore from Jinggu area in Yunnan province, a suitable technical route was presented for processing of eligible copper concentrate and the main factors i.e. grinding fineness, Na2S dosage and collector dosage, affecting the quality of roughing concentration was investigated. On this basis, a close-circuit flotation test scheme was preceded, which obtained a high quality copper concentrate with Cu grade of 16.08%, copper recovery of 58.52%. The recovery of copper concentrate is much lower than the Cu recovery of roughing concentrate from the condition experiments. This may be contributed to the fact that fine slime carried by middling worsens the separation of copper minerals and gangues. The Mo was enriched in concentrate, which is significantly considered to recovery in further work.

In this study, the effects of important factors on malachite exploited from Tibet are investigated. Dosages of activating agents, depressants and collectors are essential to the effective recovery of copper in the flotation. The mixed collector ratio of SIBX: Armac C was varied as 0:1, 1:1, 1:2, 1:3, and 1:4. This investigation showed that using Armac C in conjunction with traditional SIBX collectors can successfully simultaneously recover copper oxides by flotation. The rougher scavenger copper recovery was as high as 85.2%.

To establish the flotation response and suitability of the collectors, series of bench-scale flotation tests are conducted for the refractory oxide copper ores obtained from Yangla Mine in Yunnan province. A simple xanthate (PAX) is used as the sulphide collector and a chelating reagent of hydroxamate AM28 as the oxide collector. It is found and confirmed by mineralogical examination that AM28 successfully recovered all the discrete copper oxide minerals from the Yangla ore. The flotation tests show that the overall copper recovery is affected due to the minerals copper associated with goethite which is not amenable to flotation. The average copper recovery from the rougher tests is 38.4% with a concentrate grade of 3.19%. The additional cleaning flotation can increase the Cu grade in concentrate further.

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%.
