The Beneficial Effects of Feeding Dry Copper …
furnace needs 7.4 GJ/h for the dry concentrate. The difference between drying wet feed in a smelter and a steam dryer amounts to 67.9 GJ/h of energy. This energy raises the off-gas temperature from 115°C to 1200°C, which is actually energy wasted. Drying the feed before smelting can save this energy, equivalent to 13 800 tons of heavy oil per ...
