Environmental evaluation of metals and minerals
It is important to know that minerals have a lower impact than metals (except copper and lead ore) based on one mass units. This is essentially due to smelting and refining which are intensive energy consuming processes necessary for metal refining. Refined gold has the highest impact on GWP with an average value of 2.65x10 7 kg …

Nickel Smelting And Refining Industry
Older nickel-smelting processes, such as blast or reverberatory furnaces, are no longer acceptable because of low energy efficiencies and environmental concerns. In flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (30–40% oxygen), or pure oxygen.
