Recyclability and Energy Efficiency:The Case for Copper in

Copper's Energy Efficiency . Overall energy consumption for aluminum and copper varies from study to study see Table 1, but the values for aluminum are fairly consistent except in one or two instances where estimates are based on water power electricity and no losses are reported.A normal value for aluminum is 75 MWh/t for primary metal and 5 MWh/t for recycling clean scrap.

Copper FlotationMineral Processing & Metallurgy

Porphyry copper ores, usually medium to medium hard, require grinding to about 65mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.
