Study on the Migration Rules of Sb in Antimony Ore Soil Based on HYDRUS-1D

Abstract

In the surrounding soil of areas of antimony ores mining, mineral separation, and smelting, the content of antimony increases markedly, and the reason is on the one hand, in the mining and separation process of antimony ores, native antimony ore residual particles formed by antimony-bearing rocks and the formation of secondary minerals result in antimony obviously being enriched in the surrounding soil of mining areas [1-2]. On the other hand, the "three waste" materials produced in the mining, separation, and smelting processes of antimony ores become an important source of soil antimony pollution around the mining areas through the wet and dry deposition of atmosphere, rain leaching of waste residues, and waste water irrigation [3-4].

Source identification and groundwater health risk assessment of PTEs in the stormwater runoff in an abandoned mining area

“…Use HYDRUS-1D to simulate soil PTEs transport HYDRUS-1D could be used to simulate the movement of water, heat, and multiple kinds of solute in a variably saturated soil (Simunek et al, 1998). A soil antimony transport study in Xiangtan Manganese Mine also obtained good simulation results with HYDRUS-1D (Zhang et al, 2019). HYDRUS-1D used two main equations to calculate moisture movement, Richards' equation and Van Genuchten equation.…”

Detection of Landfill Leachate Leakage Based on ERT and OCTEM

“…Therefore, landfills are often required to conduct noninvasive leak detection. Traditional leakage location detection methods, such as alternating electrical current detection, affect the accuracy of terminal detection results because of the electromagnetic crosstalk between transmission lines [37][38][39][40][41][42][43]. The disadvantage of the dipole method in the direct electric current method detection system is that the current significantly attenuates with an increase in measurement distance, that is, the covering the thickness and conductivity of the waste layer affects the potential distribution.…”

Simulation of Manganese Transport in Groundwater Using Visual MODFLOW: a Case Study from Xiangtan Manganese Ore Area in Central China

“…Under the combined action of rainfall scouring and leaching, the heavy metal elements in tailings have various physical and chemical reactions, such as diffusion, dispersion, desorption and dissociation, forming the pollution source of tailings pond [5]. This material, driven by surface runoff migrates into the subsurface [6,7] and enters the water environment of the surrounding areas leading to wider potential exposure and risk to human health and economic development [8][9][10].…”
