Soil pollution, soil erosion, dust pollution, and ecosystem destruction are common problems faced by all mines. Nitrogen (N), phosphorus (P), and potassium (K) are nutrients necessary for plant growth in the soil. Almost all mined mine soils lack N, and many also lack P and some trace elements. At the same time, the texture of mined mine soils is usually hard, with particle sizes ranging from sand to clay. The coarser parts usually have poor buffering capacity, lack organic matter and nutrients, have low water holding capacity, and are very prone to drought and water shortage. These lands are difficult to maintain seed germination and seedling growth, so it is difficult to restore vegetation. In particular, after sulfur-containing mines (sulfur mines, coal mines, metal mines, etc.) are mined, the generation of heavy metal and AMD pollution in the soil may last for centuries. The pollution is long-lasting, the pollution area is wide, and the restoration is difficult, which has become the current research focus of mine restoration.
Chemical remediation mainly includes immobilization/stabilization technology and soil washing technology, and its main purpose is to solve the problem of high ecological and environmental risks caused by soil heavy metal pollution. The main purpose of immobilization/stabilization technology is to reduce the mobility and effectiveness of heavy metals in mine soil, and the main purpose of soil washing technology is to remove heavy metals in mine soil.
Soil washing technology mainly refers to the use of chemical extractants to separate or remove pollutants from mine soil and concentrate them into extractants to achieve the purpose of remediation. Commonly used heavy metal extractants include inorganic acids such as nitric acid or hydrochloric acid, inorganic salts such as ferric nitrate, calcium chloride, etc., organic acids such as citric acid, chelating agents such as EDTA or DTPA, among which EDTA is one of the most studied typical extractants in recent years. Compared with other chelating agents, EDTA has a low rate of degradation by microorganisms in soil and a high complexing ability with heavy metals.
