• Description:
  This report is a comprehensive evaluation of a Bureau of Mines developed induction balance sorting machine for separating rock fragments that contain metal from those that do not. The machine was evaluated using run-of-mine ore containing native copper from the Kingston and Centennial Mines, and waste rock that contains copper metal from the Champion Mine. The tests show that the sorter is capable of sorting efficiencies of 9.15 pct with a 97+ pct availability. Calculations suggest that if the capacity of the machine can be increased, the cost of mining native copper ores could be reduced. [Description provided by NIOSH]
