Abstract Scope |
A novel process was developed and implemented to reduce sulphur dioxide generation during the electric furnace smelting stage of the smelter at Glencore’s Sudbury Integrated Nickel Operations, located in Ontario, Canada. The novel process reduced the oxygen concentration in the furnace freeboard, thereby reducing unwanted roasting of residual sulphides in the furnace feed. A program of increasing-scale testing verified and demonstrated the viability of what was dubbed the Controlled Furnace Atmosphere (CFA) process. A significant reduction of site annual emissions has been achieved since the commercial installation in 2015. Capital cost per tonne of emission reduction was lower than market-proven alternatives, and operating cost was minimal. This presentation will describe the development and subsequent commercial operation of the new CFA process. |
