The main benefits of sidewall copper cooling include:

• Forming and maintaining a stable slag freeze lining, extending the furnace lining campaign life.
• Higher furnace power intensity is possible, increasing furnace energy efficiency and throughput.
• Freedom to optimize the process chemistry and operating parameters to maximize throughput and recoveries with lining life considerations being less of a constraint.
• Longer furnace campaigns will help to improve availability, lower overall capital expenditure, and reduce long-term operating costs.
