Mine Tailing
Mine tailings are typically silt-sized materials derived from mineral processing, which are conventionally pumped as an aqueous slurry, thickened tailings, or a tailings paste to a surface tailings storage facility (TSF). After discharge, an aqueous tailings slurry forms a wet, soft delta, while thickened and paste tailings form a more ...Web
