The combination of different bioleaching bacterial species is known as "bacterial consortium". It is known that bacterial consortia are modified according to specific type of mineral and it environmental conditions (Rawlings and Johnson, 2007). Each kind of ore has unique characteristics, either a particular strain or a consortium of bacterial strains, which serves very well for a given mineral, but it is useless against another type of ore (Okibe and Johnson, 2004). That is why despite that already they have isolated and patented a large number of bioleaching strains; the industry continues investing in a variety of research to find new strains that achieve optimize the bacterial bioleaching
