Waste Mine Tailings Characterisation

This is especially true of the copper, iron, and uranium industries. A total of 31,191 million tons of overburden, waste rock, and tailings was generated by the metal-ore and non-metal mineral mining industries during the period 1960-1977. Of this total, approximately 40 percent was generated by the copper mining industry alone.
