Abstract

a presente invenção tem por objetivo prover um método de beneficiamento mineral utilizando biorreagentes extraídos das bactérias gram positivas rhodococcus opacus e rhodococcus erytrhopolis. nesse sentido, avaliou-se a flotabilidade mineral utilizando biorreagente extraído de bactérias gram positivas para determinar seu potencial como uma alternativa aos reagentes sintéticos e também uma alternativa ao uso dos microrganismos por si só (biomassa).
