The Challenges of Reusing Mining and Mineral-Processing

Reuse of discarded mine waste, referred to as tailing recovery, helps reduce exposure of waste to the environment and in some cases can maximize target mineral efficiency . For example, waste rock or coal slime generated after washing processes may contain carbon with calorific values of 3350 to 6280 kJ/kg, which can be remixed with coal for additional power generation ( 16 ).
