The reuse of mining and minerals processing waste, if inert, can offset the impacts that would have been generated by the replaced material, and reduce the amount of waste produced per given unit of resource. Reprocessing of waste has the potential to provide an economic opportunity to rehabilitate historical sites into stable landforms.
The primary goal for disposal of mining and mineral-processing wastes should be to ensure that the waste remains physically, geographically, chemically, …
