    Oct 15, 2020 After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods

    Jan 21, 2020 1. Introduction. Nickel is a hard, ductile, silvery-white transition metal; it is the 28th element in the periodic table. It may exist in several oxidative states (from −1 to +4); nevertheless, the +2 oxidation state (Ni 2+) is the most widespread in the environment and biological systems [].Nickel belongs to the ferromagnetic elements, and it is naturally present in the Earth crust

    Dec 19, 2016 Most mining activities induce an impact on their environment (e.g., water, groundwater) due to the presence of metal element (ME)-rich tailing deposits . The effects of contamination from abandoned mine waste occur at all levels of biological organization, and there are potential indicators at each level [22, 23]

    Uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. These tailings pose serious environmental and health risks in the form of Randon emission, windblown dust dispersal and leaching of contaminants including heavy metals and arsenic into the water.
