A method for extracting highly dispersed gold from aqueous mineral suspensions includes treatment with bioflocculant on the basis of biomass of microorganisms with subsequent separation of the dispersed phase enriched with gold, at that nanobiocomposite is used as the bioflocculant, and this nanobiocomposite consists of intact cells of microalgae Chlorella vulgaris Brijer. and nanoparticles of iron compounds, produced by treatment of the microalgae biomass with iron-containing electrolyte, and this nanobiocomposite contains iron in an amount of 0.1-1.0% wt. per dry basis. |
