Mine waters and tailings generated from mining and mineral processing activities often have detrimental impact on the local environment. One example is acid mine drainage, in which sulphides in the mining waste react with water and oxygen to produce an acidic environment that subsequently dissolves host rock minerals from the waste containing toxic metals and trace elements. Copper is one such ...
Mine tailings pose physical and chemical challenges for plant establishment. Our aim was to learn from natural processes in long-term soil ecosystem development use as novel parent materials pioneer ecological-engineering species ameliorate extreme conditions of tailings, facilitate the establishment subsequent native plants. A glasshouse trial conducted using magnetite containing various amend...
Dust from uncovered mine tailings at Giant mine, an abandoned in northern Canada, has been a concern for nearby residents. We have utilized microanalytical mineralogical analysis combined with quantitative measurements of phase distribution and bulk concentration to fully characterize the dust currently generated tailings. Surface material was sampled three impoundments on site sieved <63 μm as...
Abstract La Parrilla is a tungsten and tin mine located in western Spain. The tailings facility has total capacity for 3 Mm will be executed four different phases. main constraint the design construction of dam that it been constructed over an existing one from 1980s. activities involved removal substitution old southern portion facility, ground improvement with gravel columns area about 10,000...
The Tongon mine generates millions of tons waste rock and tailings, which are stored in landfills the vicinity mine. These tailings contain arsenic. risk soil contamination this area is evident. This study assesses arsenic soils around health risks to local population. Soil samples were taken from plastic bags other materials used as working tools. Arsenic concentrations determined by inductive...
The particle size and content of tailings are important parameters affecting the rheological properties slurry. To explore their influence law mechanism on properties, experiments slurry were designed carried out under different sizes conditions. quantified in paper. Bingham body model was used texperiment. “double 30” theory (“particle 30.0 μm” “content 30%“) proposed expounded. corresponding ...
