The retreatment, or remining, of mine tailings can provide usable land, provide profits for companies and clean the environment by moving the reprocessed tailings to more advanced and well-managed facilities. Owing to changes in legislation, tailings need to be stored in facilities that are better managed and controlled than historical facilities. This means that the tailings from remined sites are sent to new tailing storage facilities (TSFs), said specialist consulting engineering firm Jones & Wagener environmental engineering closure and rehabilitation associate civil engineer Alice Harvey.
