Research Abstract

Abundance and leachability of several base metals and rare metals were identified in waste landfills. Estimation of multi-chemical composition indicated that the leaching and recovery of metals from waste must be applied during the stabilized phase of waste landfills. Feasibility of bioleaching for waste sample was examined. Efficiency of mixed culture of sulfur-oxidizing bacteria and iron-oxidizing bacteria as inoculums has been shown. Bioleaching of excavated waste from the landfill by electric incubation of iron-oxidizing bacterium indicated the efficiency of mobilization of metals contained in the waste. Waste landfills should possess high value of metal resources, indicating the high feasibility of biological metal recovery.
