“…3). Strong associations of Cu with Fe in HFOs could be attributed to co-precipitation of these metal ions between pH 4 and 9, a phenomenon well-known in ore genesis, hydrometallurgy, and treatment of acid mine drainage (AMD) and municipal/industrial wastewaters (Igarashi et al, 2020;Tomiyama et al, 2019Tomiyama et al, , 2020Veiga et al, 1991). Igarashi et al (2020), for example, noted that the removal of Cu 2þ and Zn 2þ in AMDs occurred via their coprecipitation with HFOs rather than as distinct and separate Cuand Zn-oxide minerals.…”

“…Pyrite oxidation is the main acidity producer of the system (Equation 1). The acidity produced by these processes may result in a pH decrease [55][56][57][58][59]. Tailings from copper porphyry-type ore deposits show 1-3% pyrite concentrations [54].…”

This paper intends to validate the application of magnetic techniques, particularly magnetic susceptibility, as sampling tools on a copper tailings terrace, by correlating them analytically. Magnetic susceptibility was measured in both the field and laboratory. Data obtained allowed for designing spatial magnetic susceptibility distribution maps, showing the horizontal variation of the tailings. In addition, boxplots were used to show the variation of magnetic susceptibility and the concentration of the elements analyzed at different depths of the copper tailings terrace. The degree of correlation between magnetic and chemical variables was defined with coefficient R2. The horizontal and vertical variations of magnetic susceptibility, the concentration of elements, and the significant correlations between them show a relationship between magnetic susceptibility and the chemical processes occurring in the tailing management facility, such as pyrite oxidation. Thus, the correlation functions obtained could be used as semiquantitative tools to characterize tailings or other mining residues.

“…In particular, there are several references to soil-vegetation uptake as a tool for bioremediation in areas that are affected by mining wastes (e.g., [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]). Similarly, publications on the geochemical aspects of the transfer from source areas to other environmental compartments (soil, surface water, and groundwater) abound [ 1 , 34 , 35 ]. However, there have been relatively few attempts to explain and predict, through the application of mathematical models, these transfer mechanisms.…”

An openly accessible cellular automaton has been developed to predict the preferential migration pathways of contaminants by surface runoff in abandoned mining areas. The site where the validation of the results of the Contaminant Mass Transfer Cellular Automaton (CMTCA) has been carried out is situated on the steep flank of a valley in the Spanish northwestern region of Asturias, at the foot of which there is a village with 400 inhabitants, bordered by a stream that flows into a larger river just outside the village. Soil samples were collected from the steep valley flank where the mine adits and spoil heaps are situated, at the foot of the valley, and in the village, including private orchards. Water and sediment samples were also collected from both surface water courses. The concentration of 12 elements, including those associated with the Cu-Co-Ni ore, were analyzed by ICP-OES (Perkin Elmer Optima 3300DV, Waltham, MA, USA) and ICP-MS (Perkin Elmer NexION 2000, Waltham, MA, USA). The spatial representation of the model’s results revealed that those areas most likely to be crossed by soil material coming from source zones according to the CMTCA exhibited higher pollution indexes than the rest. The model also predicted where the probabilities of soil mass transfer into the stream were highest. The accuracy of this prediction was corroborated by the results of trace element concentrations in stream sediments, which, for elements associated with the mineral paragenesis (i.e., Cu, Co, Ni, and also As), increased between five- and nine-fold downstream from the predicted main transfer point. Lastly, the river into which the stream discharges is also affected by the mobilization of mined materials, as evidenced by an increase of up to 700% (in the case of Cu), between dissolved concentrations of those same elements upstream and downstream of the confluence of the river and the stream.
