An investigation of the potential for eucalyptus oils as reagents in fine coal flotation

, 2010
Natural oils such as pine oil and eucalyptus oil were used in metalliferrous flotation, principally as frothers, in the early days of flotation In recent years synthetic collectors and frothers have taken over, largely because the complex chemistry and ...

A study of the interfacial chemistry of pyrite and coal in fine coal cleaning using flotation

, 1993
Surface oxidation, surface charge, and flotation properties have been systematically studied for coal, coal-pyrite and ore-pyrite. Electrochemical studies show that coal-pyrite exhibits much higher and more complex surface oxidation than ore-pyrite and ...

Pyrite–Coal Depressants Interactions During Coal Reverse Flotation

This work investigates coal desulfurization by using reverse flotation. In this method, pyrite (the only source of sulfur in the studied coal) was separated from the meta-bituminous coal by using three different coal depressants (starch, dextrin and ...

Coal recovery from waste fines of the Nuraxi Figus coal treatment plant by selective flotation

, 2005
In this study we have used wet separation techniques for selective flotation of the low rank Sulcis coal. The investigation has been carried out for cleaning waste coal fines from the Nuraxi Figus treatment plant with a view to using the concentrate in
