| Abstract: | This paper studied different oxidation surfaces and modified surface of coal-pyrite, which was collected from Zhongliangshan ore in Chongqing, by using X-ray diffraction(XRD) It is found that with increasing pyrite surface oxidation its oxidized products are FeS x , FeS and S 0, and then, the area of fresh surface will decrease On the contrary , if the oxidates on FeS 2 surface is reduced to hydrophilic S 2- using different methods, the desulphurization efficiency will be gradually improved Different XRD data of surface modification products were given out Three reduction waysactive metal powder, C 6H 6O 3, and electrylic reductionall tended to the same result of pyrite surface modification Surface products in different electrochemical conditions were also deduced from XRD data before and after modification It provided a theoretical foundation for the separation of coal-pyrite in flotation |
| Keywords: | pyrite surface oxidation electrochemical modificatio |
