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 ).
