“…Yangla copper deposite in Yunnan province, situated in the middle section of Jinshajiang tectonic belt between Zhongza-Zhongdian plate and Changdu plate, is a representative and giant copper deposite that has been discovered in recent years. Metalliferous minerals consist of copyrite, pyrite, pyrrhotite, galena, bismuth, bismuthinite, arsenopyrite, cobaltite, molybdemite and so on [1]. The refractory Yangla copper oxide ores are mainly present in supergene deposite where copper minerals are progressively oxidized until at or near the surface.…”

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.

In the Baiyun Sag, the oil relationship with possible source rocks is complicated, and little research on oil sources in the area has been performed. In this paper, geochemical studies of carbon isotopes, biomarkers, paleoenvironmental deposition, and crude oil maturity, carried out with the use of oil samples from the Baiyun Sag, demonstrate that the organic matter in crude oil has an oxidizing depositional environment and primarily lacustrine facies conditions, with a significantly higher plant input. The oil samples used are mature to highly mature. Crude oil in the northern area of the Baiyun Sag is more mature than samples in the eastern part of the sag. Despite limited source rock data, we were able to conclude that the crude oil samples were derived mainly from the Enping Formation; other potential source rocks of the Wenchang and Zhuhai Formations may also have contributed to the reservoirs in different parts of the sag. Furthermore, the source of crude oil in each structure in the Baiyun Sag was analyzed; for example, crude oil in the LH19-5 structure was generated from the organic matter of the Enping Formation, and crude oil in the LW3-1 structure was derived from the mixed organic matter of the Enping, Wenchang, and Zhuhai Formations. © 2018, V.S.
