Web30 Apr 2024 · The mine tailings being the wastes from rocks and minerals processing, are generally rich in Si, Ca, Al, Mg, and Fe, and also have considerable amounts of heavy metals and metalloids such as Pb, As, Co, Cu, Zn, V, and Cr. When tailings contain sulphide minerals, it may also lead to acid mine drainage. WebThis paper presents a case study of the investigations and testing relating to the design and pro-gressive implementation of remedial stabilization measures for the historical tailings facility at the New Afton Mine located in British Columbia, Canada. It was necessary to evaluate both the geotechnical conditions (soil characteristics) of the tailings mass, as …
