The possibility of selective heterocoagulation of Bacillus cereus cells and nanosize gold particles in the presence of other minerals is shown. As revealed, the cell is the base element determining the charge of forming biomineral floccule and the composition of relevant mineral components. High efficiency of bioflotation in the processes of gold extraction from the dilute suspensions of gold-containing ores is shown.
