Summary

Rio Tinto's 225MUS$ SPL treatment plant in Arvida, Canada, utilizing the Low Caustic Leaching and Liming (LCLL) process, marks a decade of innovation in industrial operation. This technology addresses the global challenge of spent potlining (SPL) management by offering significant energy savings and enhanced by-product valorization.

Key Features:

- Versatile SPL Treatment: The 80kt/y LCLL plant can process various SPL sources, including Söderberg, prebaked, fresh, and mixed cuts.
- Efficient Pollution Elimination: LCLL effectively treats SPL to eliminate toxic pollutants.
- By-Product Utilization: By-products, such as carbon by-products (CBP) and caustic solution, are valuable feedstock for other industries like cement and Bayer processes.
- Process Improvements: Continuous R&D has led to 2018 breakthroughs in evaporation/crystallization and causticisation sections, resulting in:
- 40% steam consumption reduction.
- Improved CaF2 (LCLL spar) quality.
- Cost Efficiency: Optimized LCLL process lowers total OPEX costs below landfill expenses. Simplified design also reduces CAPEX for new plants.
