A mix design, using a mixture of sand and mine tailings as aggregates, was selected to produce a cement-based 3D material suitable for building purposes. Different dosage rates of mine tailings, water, superplasticizers, and accelerators were added to the mixture with the end of looking for the optimum strength, workability and …

If mining tailings are not properly sealed, they can cause soil and water contamination due to the deposition of metals or other elements [13]. The risks posed by mine tailings are related to environmental factors, such as temperature, wind, and precipitation, which affect the dispersion of metals and other elements from Cu mine …
This study investigates copper ore tailings deposited in Repparfjorden, Norway in the 1970's. Bathymetric show that the tailings deposit still occurs as a series of cone-shapes and has retained its original shape for four decades. Analytical data of 51 chemical elements show that some of the tailings are spreading, affecting fjord surface ...

The arsenic concentrations were comparable with other mining-related sites worldwide, e.g. Spain, China, South Korea, Poland and Mongolia among others. Iron, As and Cd in the tailings and discharges from treatment facilities within the mine have been removed by 82.9–94.7%.
The most effective extraction of copper (84 to > 90%) was achieved by bioleaching the tailings from Bor, Serbia and Sevilla, Spain at 45 °C, using a defined thermo-tolerant microbial consortium and addition of elemental sulfur allowing for a low pH 1 (Falagán et al., 2017). ...

The century-old operation, which is the world's largest underground copper mine and the sixth biggest by reserve size, is undergoing the construction of a new level, which is …
The sulfide oxidation and precipitation of Al-Fe-secondary minerals associated with abandoned acid mine drainage (AMD) from the abandoned copper mine waste pile at Touro, Spain, has been studied ...
Soil pollution by lead, zinc, cadmium and copper was characterized in the mine tailings and surrounding soils (arable and pasture lands) of an old Spanish Pb–Zn mine. Sixty soil samples were analyzed, determining the total metal concentration by acid digestion and the chemical fractionation of Pb and Zn by the modified BCR sequential ...

Atalaya Mining has temporarily suspended usage of tailings facility at its Rio Tinto copper project in Andalucía, Spain, after receiving an information request from the Junta de Andalucía.. The company provided all relevant reports to the Junta and hopes that it will result in the lifting of the provisional suspension soon.
The tailings are pumped to the tailings pile and the copper concentrate is transported to a nearby smelter. Mill tailings may contain radionuclides due to their natural presence in the ore bodies and thus are a potential source of TENORM. Because the pyrite/sulfide minerals are in tailings piles with an exposed surface area, they may be ...
