Optimising SAG Mill Productivity at Sossego: A Technical Analysis of Molycop Tools
The Sossego copper-gold mine in Brazil has emerged as a critical case study in mining operational efficiency, demonstrating remarkable improvements through advanced technological interventions. Located in Canaã dos Carajás, this significant mineral production site has successfully addressed complex grinding challenges through sophisticated simulation technologies and strategic process optimisations.
The Sossego Mine: Geographic and Operational Context
The Sossego Mine, owned by Vale SA, represents a pivotal asset in Brazil's mineral production landscape. Producing approximately 66,800 tonnes of copper in 2023, the mine has consistently demonstrated its strategic importance in the global copper market. Its geological setting in Canaã dos Carajás presents unique challenges that demand sophisticated processing technologies.
The copper-gold deposits in this region are characterised by high-grade ores with complex mineralogical compositions. These deposits require advanced processing techniques to ensure optimal mineral liberation and recovery. The challenging geological context necessitates precise grinding strategies to maintain economic viability and production efficiency.
Technical Challenges in SAG Mill Operations
Processing facilities at Sossego encountered significant operational bottlenecks related to grinding fragmentation. The primary challenges included suboptimal grinding media trajectories and inefficient mill liner strategies. These technical limitations directly impacted overall plant productivity and energy consumption.
Molycop's intervention focused on addressing these specific operational constraints through advanced simulation technologies. By evaluating multiple scenarios, the team developed a comprehensive approach to enhance SAG mill performance. The simulation process examined critical parameters including:
- Liner conditions within the SAG mill
- Potential adjustments in mill rotation speed
- Grinding media trajectory dynamics
Optimisation Strategies and Performance Outcomes
The technical team applied sophisticated simulation methodologies to evaluate potential performance improvements. By increasing the mill's rotation speed to 80%, significant efficiency gains were achieved. The results were remarkable, with a 9.8% improvement in milling energy consumption.
Detailed analysis of internal load dynamics provided critical insights into grinding processes. These customised evaluations enabled precise recommendations for liner and media management strategies. The approach demonstrated how targeted technical interventions could deliver transformative operational results.
