BACKGROUND Artificial aeration plays a pivotal role in the bioleaching of sulfide ores by influencing microbial activity, oxygen supply, and mineral dissolution kinetics. However, the quantitative relationship between aeration rate and leaching efficiency for low‐grade copper sulfide ores, particula...
