As soil particle in the vicinity of Daebong mine became finer, concentration of heavy metals increased, especially arsenic(As) and lead(Pb) excelling worrisome level of 1st area in Korea. As and Pb were concentrated in less than 150 μm of particle size. Among metal compounds found by sequential extraction, the residual phase of As and Pb were about 50% and 20%, respectively. The minerals (lavendulan containing As, lanarkite containing Pb and guitermanite containing As and Pb) were identified though XRD. As a result of (-150 μm) soil purification experiments, the removal efficiency of As and Pb only using soil washing were 23% and 50%, respectively. The removal efficiency of As and Pb only by reverse flotation were 38% and 43%, each. However, when soil washing after reverse flotation, the cumulative removal efficiency of As and Pb were maximum 56% and 75%, respectively. Thus, in the combination of reverse flotation and soil washing, soil contaminated with metals could be remediated to meet the worrisome level of 1st area.
