Energy efficiency • Energy intensity in copper and gold mining

The greatest energy input in copper and gold production is required for the comminution and grinding processes. The energy audit of mainly Australian copper and gold mines shows that 36 % of the overall energy consumption is attributable to comminution [1]. Previous studies had shown values between 18 % and 50 %.
