Case Study: Mosaic Corporation achieves over 50% higher phosphate rock production with Minitab

Mosaic Corporation boosts Wingate Mine rock recovery to over 80% with Minitab

Mosaic Corporation, a leading producer of phosphate crop nutrients, faced a significant challenge with the low productivity of its Wingate phosphate mine. The mine's rock recovery rate was only 47%, far below the industry average, which threatened its long-term viability. To address this, Mosaic employed its Six Sigma team and used Minitab Statistical Software to analyze the process and identify areas for improvement.

Using Minitab's capability analysis and design of experiments features, the team was able to quickly evaluate multiple factors and implement changes to the beneficiation process. The solution implemented with Minitab delivered dramatic results, increasing the recovery rate to over 68% within 30 days and eventually to over 80%. This led to a financial impact of $12 million per year from increased production and cost savings, securing the mine's future.
