The bio-column flotation of coal for desulphurization and comparison with conventional and column flotation

Tosun, Yıldırım İsmail; Rowson, Neil A.; Veasey, Terry (1994-10)

Coal desulfurization of a type of British coal, containing 3% total sulfur, by bio-oxidation of surfaces of pyrite particles in the coal during column flotation was investigated. Growth of bacteria occurred in Tuovinen&Kelly ...
The Comparison of Chemical and Biological Suppression on Pyrite Surfaces During Coal Flotation

Tosun, Yıldırım İsmail; Rowson, Neil A.; Veasey, Terry (1992-09)

Two types of high sulfur British coals were subjected to desulfurization tests involving both chemical and bio-oxidation treatments prior to coal flotation experimentation. The fficiency of the chemical oxidation of pyrite ...
The Effect of Chemical and Bacterial Suppresion of Pyrite During Coal Flotation

Tosun, Yıldırım İsmail; Rowson, Neil A.; Veasey, Terry (1992-03)

This work studies the ffect of biooxidation and chemical suppression on the floatability of pyrite in selected coals. Initial experimental work involved the optimization of a standard coal flotation systems using a Leeds ...
