When comparing experimental EKR results on copper mine tailings of different age, differences in copper removal were found despite similarities in mineralogical composition and pH. The best copper removal from a mine tailing sample of more than 20 years of age was when applying a pretreatment of strong acidic acid and using the classical EKR setup.

Copper mining and refining generate a huge quantity of copper tailings and slags. The total copper slag produced between 1999 – 2019 is estimated to be 752 million tons (ICMM, 2019; Phiri et al., 2022). A large volume of copper tailing has potential hazards such as tailing pond failure (Kostaschuk et al., 2021).

Copper is a key resource in modern industry and society. However, copper is finite like all natural resources, and increasing demand for this material depletes global copper reserves. Recovering copper is a crucial strategy to keep up with demand. One approach is to reprocess mining tailings to extract the vital copper resources within.
