  What drives GHG emissions from copper production? — Resourceful Paths

  20161123 · The grinding media use is typically 1 kg steel/t ore, and assuming 2 t CO2e/t steel consumed, this results in about 0.3 – 0.6 t CO2e/t Cu produced of embedded emissions. This means that copper in concentrate production at an open pit mine site typically results in around 5.5 – 9.5 t CO2e/t Cu if powered by diesel and coal fired power, …
