Good article that shows how mine dumps can be reclaimed to support human use (drive in) and how re-mining of wastes can be feasible in some cases

Yeah, often mines produce more than one metal. Copper and Zinc, or copper and molybdenum are often produced together. Similarly, gold and silver are often produced together. The issue is that there are still residual metals that are not extracted or are only partially extracted, with residual levels beyond those that are safe for human health.
