Changes in cell density and pH during bioleaching of low grade copper ores from Chambishi and Dexing with Chambishi strains (solid lines) and Dexing strains (long dash lines). Evolution of cell densities in pure and mixed cultures during the bioleaching of (a) Chambishi and (b) Dexing samples; changes in pH in pure and mixed cultures during the bioleaching of (c) Chambishi and (d) Dexing mineral samples.
