PAPER OPEN ACCESS Screening of bacteria for coal beneficiation
Coal biobeneficiation was carried out to investigate the changes in the total sulfur and ash in coal after treatment with bacteria (Table 1). It was found that the total sulfur content of the initial coal sample was 2.82%, and under optimal condition, 15.25% and 16.31 ...
Biobeneficiation of Iron Ores
2/1/2012· Biobeneficiation processes are more environment-friendly than physico-chemical alternatives. For example, many of the microorganisms reported to be useful in iron ore beneficiation are also implicated in bioremediation through degradation of organic reagents.
Biobeneficiation development for the reduction of .
The important part of this finding is the discovery of a cheap microbial energy source (spoilt grape) that can be further exploited for full biobeneficiation of iron ore minerals. Another advantage of this method is the fact that the experiment can be conducted under non–sterile conditions, making it a system that can be operated outdoor.

biobeneficiation
Biobeneficiation can be achieved by bioflotation and bioflocculation, where microorganisms render a mineral surface more hydrophobic or hydrophilic and/or change the surface charge of the mineral. In biobeneficiation, the microorganisms and/or their metabolites can act as modifiers, collectors, and depressants ( Botero et al., 2007 ).
