Observation Results

We investigated the characteristics of metal(loid) transport and dispersion in agricultural soils near an abandoned metal mine. Topsoil samples were collected from 162 sampling sites in the study area, including 1 in the mine tailing dumps, to analyze the total concentrations of As, Pb, Cd, and Zn. Subsequently, the metal(loid) transport and dispersion characteristics were investigated using geographic information system (GIS) technology. The results of this study clearly demonstrated the variation in the dispersal of As, Cd, Pb, and Zn from the mine tailing dumps to nearby agricultural soils and the element-specific spatial variability in their respective transport and dispersion characteristics. These findings suggested that compared with the migration behavior of Cd, Pb, and Zn, that of As has a farther-reaching impact on agricultural soils owing to its geochemical cycling in the soil and groundwater environment. This impact differed significantly in magnitude from that of the other investigated metals. Therefore, special consideration must be given to the migration behavior of As.

Harmless Disposal

Manganese mine slag was the salvage in the course of manganese producing. Many matters shall be extracted by rain eluviation and then turn into the water and soil to pollute environment. The water content and extraction procedure toxicity of the manganese waste residue were studied. Combining solidification additive was used to process the manganese waste residue for the harmless disposal. The results showed that the contents of Manganese、Zinc、Chromium and Cadmium in the manganese waste slag exceeded the maximum of the Chinese Identification standard for hazardous wastes. The extraction procedure toxicity was effectively decreased by the harmless disposal when the proportion of cement and manganese in the whole mine slag was 60%, and the content of heavy metals in the leaching solution were under the standard. Hence, the method of cement solidification could control the pollution to the environment effectively.
