Heap leaching is a well-established mining technology that involves stacking crushed ore into piles situated on an impermeable layer equipped with a drainage system. This study examines the principles, mechanisms, and dynamics of chalcocite heap bioleaching. The objective is to provide a detailed overview of the process, particularly focusing on the bioleaching of copper oxide minerals utilizing microbial activity. Methodologically, the analysis encompasses historical context, operational techniques, and parameters influencing microbial growth within heap bioleaching, including in-situ drainage and nutrient supply. Results indicate that heap bioleaching has effectively been implemented since the 1980s, initially at Lo Aguirre in Chile, and has gained traction in numerous other mining operations globally. The study highlights how bioleaching microorganisms naturally facilitate the extraction of metals without the need for extensive external intervention, thus presenting an environmentally friendly alternative in metal recovery. By enhancing the microbial environment, the efficiency of metal extraction in heaps can be significantly improved. This research contributes valuable insights into the benefits and applications of bioleaching in the modern mining sector.
