  The bioleaching behaviour of low-grade bauxite ore of pail deposits (Khushab), Pakistan using different strains of Aspergillus niger (NRRL567, NRRL1737 and NRRL605). X-ray diffraction examination of ore revealed the presence of a number of silicate and aluminosilicate minerals. Average content of alumina in test ore was 40%. Decrease in pH i.e. in the range of 2-2.4 was observed due to organic acids produced by A. niger strains during growth on liquid media containing glucose. Fungal nutrient requirement was unsatisfied at final media glucose concentration of 5%. Maximum of ~4g/L Al2O3 was solublized having bauxite pulp density 5%. Scanning electron microscopy along with electron disperse X-ray analysis (SEM-EDX) reflected significant alumina solubilization.

  The research work deals with the examination of the dissolution of aluminum from low grade bauxite of pail deposits (Khushab) with different penicillium strains. X-ray diffraction data indicated the presence of silicate and aluminosilicate minerals. Scanning electron microscopy and electron disperse X-ray analysis showed the presence of aluminum iron silica and titanium. Decrease in pH in the range of 3.40 was observed in liquid growth media inoculated with Penicillium strains (Penicillium simplicissimum and Pinicillium sp. UAF1) due to the production of organic acids. About 4.6 g l-1 Al2O3 was solubilized having bauxite pulp density 5%.
