Copper sulphide ores containing chalcopyrite are challenging to leach under atmospheric conditions, prompting the need for alternative hydrometallurgical treatments, such as pressure leaching. This study aims to optimize the performance of pressure leaching circuits through two main strategies: enhancing the configuration of autoclaves and improving the heat removal method. The methodology involves creating an autoclave model that incorporates mass balance principles and the kinetics of leaching reactions, focusing on the shrinking particle model. By applying this model, the research demonstrates how adjustments in autoclave design and heat management can lead to more efficient extraction processes for copper recovery from chalcopyrite ores. The results indicate a significant improvement in leaching efficiency, underscoring the viability of pressure leaching as an effective method for processing low-grade copper ores. Ultimately, this work contributes valuable insights for the design and optimization of pressure leaching circuits in industrial applications.
