Tailings management handbook. A life-cycle approach / Руководство по управлению хвостохранилищами. Подход, основанный на жизненном цикле

Tailings are a waste product of the mining process. Described simplistically, material excavated from the mine is categorized as either ore or waste, and waste is generally hauled to a waste rock storage facility while ore is hauled or conveyed to a mill and plant for processing. Ore is processed to extract a desired commodity and the remaining material is considered tailings, which also includes any chemical additives and water that may have been used during processing. Water may be recovered from the tailings and recirculated through the process plant prior to transporting the tailings to a tailings storage facility (TSF) or using the tailings as backfill for underground mine voids. <...>
