What drives GHG emissions from copper production

Nov 24, 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.
