%X Bioleaching of Ni, Cu and Co from the Jinchuan low-grade NiCuCo sulfide ore has been investigated with aerated leaching, agitated leaching with air bubbling, and column leaching respectively. The highest recovery was achieved in the aerated leaching. Leaching 20 d with pulp density of 15%, the leached Ni, Cu and Co were 95.4%, 48.6% and 82.6% respectively. By agitated leaching with air bubbling for 14 d at the pulp density of 25%, the leached Ni, Cu and Co were 80.2%, 45.2% and 78.4% respectively. With column leaching for 49 d, the leached Ni, Cu and Co were 48.5%, 37.5% and 33.6% respectively.
