Kinetic comparison of biological and conventional flotation of coal

, 2009
Froth flotation is commonly used in coal processing to selectively recover the organic material (coal) from inorganic waste material. Tabas coal, located in east Iran, contains fine disseminated pyrite which is floated with coal during flotation, and ...

Application of Acidithiobacillus Ferrooxidans in Coal Flotation

, 2009
Bioflotation is a potential method for removing pyritic sulphur from coal. Sodium cyanide is a well-known depressant for pyrite in flotation of sulphide minerals; however, for coal this reagent is unacceptable from the environmental point of view.

Emulsified flotation: Does higher emulsion stability lead to better low-rank coal flotation performance?

International Journal of Coal Science & Technology
The flotation of low rank coal (LRC) is an important method to achieve LRC clean utilization and environment sustainable development. Emulsified diesel (ED) is an effective LRC flotation collector, but the instability limited its industrial application ...
