This means that the leach residues will contain sulphides that would trigger acid mine drainage (AMD) and a significant amount of recoverable metals.

Biomining - Wikipedia

Biomining is the technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.
