“…The geoaccumulation index (Igeo) was developed by Müller (1979) [42]. It compares the measured concentration of the elements in tailings; with geochemical background [55] The Igeo expression is show in Equation (1).…”

“…Mining environmental liabilities (MEL) are elements such as facilities, infrastructures, surfaces affected by spills, disturbed watercourses, machine shops, tool storages, storages, mining waste deposits or stockpiles currently located in abandoned mines that pose a permanent potential risk for human health and the environment [1][2][3].…”

“…The absence of clear regulations has led the accumulation of MEL in mining zones worldwide. There are polluted areas due to the mining activities that have been carried out for centuries in different countries such as Peru [1][2][3][4], Mexico [5], Chile [6], South Africa [7], Ghana [8], Slovakia [9], Korea [10], Spain [11], and Ecuador [12][13][14][15][16]. Moreover, numerous MEL have been reported in Latin American countries such as Bolivia, Chile, Colombia, and Peru [17].…”

In Chile, metal mining is concentrated between the Administrative Regions IV and VI (which includes the Metropolitan Region). The northern and central zones of the country have abundant copper as well as mineral iodine and iron. Today, these residues are stored in tailing dams. Mine tailings constitute the toxic residues composed of trace elements, which in many occasions are deposited in areas neighboring human settlements and are a health hazard for the inhabitants In this work, the concentrations of trace elements such as: Al, As, Cd, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Zn were studied in 6 sites of the tailings located within Andacollo city, Northern Chile.The sampling points were recorded using GPS geographic coordinates and, in the laboratory, they were characterized determining: pH, electrical conductivity, soluble organic carbon, total organic carbon, available phosphorus, boron, total nitrogen and capacity cation exchange. The concentrations of trace elements in tailings samples, were quantified by atomic absorption spectrophotometry (AAS).Potential anthropogenic hotspots were assessed using indices including enrichment factor (EF), geoaccumulation index (Igeo), contamination factor (CF), Pollution load index, (PLI), ecological risk (Ei) and potential ecological risk (PERI) index. These indexes are used to assess the presence and intensity of anthropogenic contaminant deposition on surface soil.The physicochemical characterization of the tailings allowed establishing a profile of the environmental conditions of the sampled sites. The sites that presented a higher concentration of metals correspond to sites 4 and 6.The polluted index values than indicated, high degree of contamination for Cu, Hg and Mo by other hand PLI and Ri index indicated the sites more polluted are 4,5 and 6.

“…In the case of copper mine tailings, investigations have shown that there is a high risk to health [ 17 ]. In the countries with the highest copper production, Chile and Peru, research has shown that contamination by mine tailings is significant for the health and environment of the surrounding communities due to a lack of adequate management of tailings and mine closures [ 18 , 19 ]. Similarly, the countries with the largest environmental footprint in copper production are the United States, China, and Canada.…”

There is a need to define mine tailings in a clear, precise, multidisciplinary, transdisciplinary, and holistic manner, considering not only geotechnical and hydraulic concepts but also integrating environmental and geochemical aspects with implications for the sustainability of mining. This article corresponds to an independent study that answers questions concerning the definition of mine tailings and the socio-environmental risks linked with mine tailings chemical composition by examining the practical experience of industrial-scale copper and gold mining projects in Chile and Peru. Definitions of concepts and analysis of key aspects in the responsible management of mine tailings, such as characterization of metallic–metalloid components, non-metallic components, metallurgical reagents, and risk identification, among others, are presented. Implications of potential environmental impacts from the generation of acid rock drainage (ARD) in mine tailings are discussed. Finally, the article concludes that mine tailings are potentially toxic to both communities and the environment, and cannot be considered as inert and innocuous materials; thus, mine tailings require safe, controlled, and responsible management with the application of the most high management standards, use of the best available technologies (BATs), use of best applicable practices (BAPs), and implementation of the best environmental practices (BEPs) to avoid risk and potential socio-environmental impact due to accidents or failure of tailings storage facilities (TSFs).

“…environmental damage. For example, in Peru, a study on water quality measurements has evidenced the presence on sulfides in the Auri and Rimac rivers caused by small-scale mining [2]. For these reasons, water quality monitoring methods should be improved and made more intensive following government policies, such as water resource quality recovery strategies [2].…”
