Abstract
The bioleaching behavior of low-grade copper sulphides under the condition of preferential solution flow was investigated through experiments. The experiment of bioleaching of low-grade copper sulphides under the condition of preferential solution flow was conducted within the multifunction autocontrol bioleaching apparatus. The size distribution of the ore in both coarse and fine regions has investigated in this experiment. The height of the dump was measured during leaching. Three main reasons have accounted for the decrease of the height. The content of fine ore particles within both fine and coarse regions increased during the leaching period, and the preferential solution flow shift from fine region to coarse region. The surface of the ores on top of dump was attacked seriously, and the ores on the middle was attacked slightly. There were plenty of crackles on the surface of bottom ores because of the precipitation layer on the surface.
