What drives GHG emissions from copper production

Nov 23, 2016· The table above shows a worst case scenario, a typical low grade copper mine using coal fired electricity would produce in the order of 3 5 t CO2e/t Cu produced. A large open pit copper mine may use in the order of 200,000 L/d of diesel, with an emissions factor of about 2.7 kg CO2 e/L, resulting in 200,000 t CO2 e/y of emissions.

Lower-pH Copper Flotation Reagent Department of Energy

New Reagent System Improves Recovery, Reducing Energy Use and Air Emissions in the Mining Industry. In the mining industry, flotation is a process that concentrates minerals from their ores prior to metal recovery. Current practice uses slurry pHs in excess of 10, achieved by adding burnt lime (CaO).

Zero Emissions Mines Have Started International Copper

Jul 21, 2020· Of course renewable energy is just one part of the zero emissions puzzle facing miners. Mining is responsible for 10% of the country’s energy use, so cutting back not only makes environmental sense but financial as well. Transforming the mining sector-and copper in particular-is likely to take a lot more effort though.

Copper and Carbon Copper’s Contributions Towards

Generating this wasted electrical energy produces carbon emissions and consequently contributes to global warming. An important initial decision, in seeking to reduce these losses, is to use copper as the conductor. Differences in resistivity mean that a copper conductor has only 61% of the losses of the same diameter in aluminium.
