Reverse Flotation of Taixi Oxidized Coal

Energy & Fuels, 2013
X-ray photoelectron spectroscopy (XPS) was used to indicate the chemical properties of Taixi oxidized coal. The results of XPS analysis showed that Taixi oxidized coal contained many oxygen functional groups. The results of our previous studies (conventional flotation tests using diesel as collector) indicated that Taixi oxidized coal was difficult to ...

Comparison of Traditional and Zero-Conditioning Flotation Performances of Oxidized Anthracite Coal

Powder Technology, 2015
Oxidized coal is usually difficult to float using common oily collectors in a traditional flotation process. In order to float oxidized coal efficiently, this paper proposed a novel flotation process which was named zero-conditioning flotation process ...

The oxidization of coal

Coke and Chemistry, 2017
The oxidation of coal is generally explained by the radical-chain hypothesis. Detection of active centers and free radicals is possible by methods available today, and the formation of methyl, methylene, phenol, carbonyl, and carboxyl groups and their interaction with oxygen and water molecules may be described.
