This study aims to replicate and validate previous chemical engineering processes used for local phosphate production in Morocco, focusing on optimising resource utilization. A rigorous replication methodology was employed, including a detailed analysis of the chemical reaction kinetics model used in previous studies. Input parameters were varied systematically to assess variability and robustness of the process. The replicated process showed a consistent yield rate of 95% across all tested input conditions, with no significant variation observed within the uncertainty bounds of ±3%. This stability is crucial for sustainable phosphate production in Morocco. The replication study confirms the reliability and efficiency of the chemical engineering processes used for local phosphate production, providing a robust foundation for future research and implementation. Recommendation includes further investigation into long-term operational parameters to ensure sustainability, alongside potential improvements in resource management strategies.
