The interaction of sphalerite and galena with cells of Bacillus polymyxa was investigated through adsorption, electrokinetic, flotation, and flocculation studies. Adsorption experiments indicated that a higher amount of the cells was adsorbed onto galena compared to sphalerite. The adsorption densit

Biodissolution tests reveal the release of lead/zinc species from galena/sphalerite, respectively, while biosorption experiments confirm interaction of cells of Bacillus polymyxa (B. polymyxa) with the metal ions of interest. The amount of exo-polysaccharides is found to be the highest in the case o
