Mine tailing storage represents an important environmental issue. The generation and dispersal of dust from mine tailings can contaminate air surrounding soils. In addition, metals soluble salts present in these wastes could pollute groundwater surface water. recovery contribute to minimize the risk achieve a circular economy model. main objective work is study use two carbon-based materials, c...

Mercury (Hg) release from inoperative Hg mines in the California Coast Range has been documented, but little is known about the release and transport mechanisms. In this study, tailings from Hg mines located in different geologic settings--New Idria (NI), a Si-carbonate Hg deposit, and Sulphur Bank (SB), a hot-spring Hg deposit--were characterized, and particle release from these wastes was stu...

Abstract This study takes lead-zinc flotation tailings as the research object. The process of “tailings regrinding-lead-zinc mixed floatation-activation zinc separation” is used to comprehensively recover valuable metal elements from original tailings. results show that grinding fineness -74 μm under condition m accounts for 82%; recovery rates lead and in concentrate obtained open-circuit test...

Waste materials from mining tailings, often contain significant amounts of potentially valuable minerals. This study aimed at unearthing the minerals in Ijero Ekiti mine tailings. The tailing samples were randomly collected five locations area. analyzed for selected physico-chemical parameters: pH values, electrical conductivity, chloride, organic matter and X-Ray Fluorescence Spectrometry (XRF...

Toxic metalliferous mine-tailings pose a significant health risk to ecosystems and neighboring communities from wind and water dispersion of particulates containing high concentrations of toxic metal(loid)s (e.g., Pb, As, Zn). Tailings are particularly vulnerable to erosion before vegetative cover can be reestablished, i.e., decades or longer in semi-arid environments without intervention. Meta...

background: composition of dust in the air due to contact with human via inhalation, ingestion and skin absorption will have a large impact on public health. in the learning environments such as universities, many people spend most of their day in contact with the dust. the purpose of this study was to evaluate the concentration of heavy metals lead, chromium and copper in the training space of...

An arsenic resistance genomic island in the bacterium Klebsiella michiganensis 3T412C was isolated from mine tailings from Peru. This genomic island confers adaptation to extreme environments with high concentrations of arsenic. Isolate 3T412C contained a complete set of genes involved in resistance to arsenic. This operon is surrounded by putative genes for resistance to other heavy metals.
