Microbially enhanced removal of pyrite and chalcopyrite from oxide gangue minerals with reference to desulfurization of tailings
|
Abstract
The selective removal ofsulfide minerals, such as pyrite and chalcopyrite ,from oxide gangue minerals, quartz and calcite was achieved in the presence of bacterial cells and metabolic byproducts of Bacillus polymyxa. A selective affinity of the bacterial cells towards the mineral surface was observed through adsorption studies. Changes in the surface chemical behavior ofbacterial cells, as well as minerals, after mutual interaction were established though zeta-potential measur...
