The present invention relates to screening methods for using the same is provided for soil heavy metal contamination by lines and, more particularly, ferromagnetic mineral soil heavy metal contamination, while soft-magnetic mineral and selecting and salts can be classified into non-magnetic mineral soil, ferromagnetic minerals can be separated easily from sorting device, removing heavy metal contamination is widened and the door can be easily performed by using the same apparatus and for soil screening methods are disclosed. Contamination of soil pollution market, after wastewater treatment sludge (sludge), harmful substances leakage, agricultural and fertilizer, incineration, deposits (river, ocean, lake bottom) by a variety of routes such as generated through. Soil polluted soil, river, a case of the marine ecosystem, contamination of crops, contaminants may result in problems as well as the body of the absorbent rich in direct form, landfill, groundwater, [e[e] lung current, to air pollution or continuous won 4.. In particular, has a thickness of american or E other, altruism altruism, like a known cause of cancer, through cleaning of contaminated soil pollution preventing and reducing damages caused by surfactant provides many efforts were disclosed. Recent business washed and cleaned indications of heavy metal contamination reduces, a purification method used mainly the soil washing, trans-membrane extraction, the soil environments the preservation law them steel target to achieve many have a specified recovery method etc.. According to the present form an initial inverter and the polluted soil, hydrophilic (water soluble), substituted-(exchangeable), carbonate (carbonate), electrolytic and (Fe-a oxide), manganese oxide (Mn-a oxide), organic (organic), residual-form (residual) designation. In the presence of heavy metals from the soil by content ratio, behavior and toxicity of heavy metals left in air by selection and method applied, major heat treatment are the server. Heavy metal contamination and methods of reducing toxicity of additional elution method for purifying soil movable steel, soil washing, such as trans-membrane extraction are classified into. The temperature, soil washing, clarification of the polluted soil heavy metal using trans-extraction method, mineral in the form of iron and manganese oxide and a residual form heavy metals removal difficult if the failure to achieve target exhaust occurs frequently. Also, when steel recovering soil by applying water-soluble and substituted form heavy stabilization bag is provided and continuous, recovery efficiency compared the pin is persistent drainage holes. I.e., a high content of heavy metal is iron or manganese oxide form and residual-type clay high tested in a polluted soil, soil washing and the stabilizing method when applying, limited efficiency of extractive or stabilization problems etc. well purifying of the target logic device. Furthermore, soil removal of heavy metals from the non-crystalline iron or manganese oxide form of soil washing method when extracting residual form using amplifying unit pivotably solution having high water solubility. The use of a lot of wastewater treatment problems and corrosion of extracting solution having high water solubility for improving a cost within the disclosed.
