The average energy per tonne of ore, per ounce of gold, per tonne of copper, and per tonne of copper equivalent can all be used to calculate the remaining energy requirement. Using the average of all three methods, the annual comminution energy consumption for the mining of copper and gold is approximately 44 terawatt hours.

On start-up, Line A, treating copper zinc ore, produced design tonnage on the first shift, made saleable concentrates of copper and zinc on the first shift, and did not shut down for 30 days. This proves design tonnage from day 1 is possible and should be the design objective for every plant, including those plants using SAG mills.

The ore sample used in this investigation was a porphyry copper ore from Chile. The ore was supplied as SAG mill feed and subsequently screened into a −53.0+9.5 mm size class. Two representative samples of approximately 30 kg were then split by rotary sample divider to provide the test samples for untreated and microwave-treated material.
