Thereby, an improved understanding of copper tailings behavior results which simplifies filtration plant operation. Copper tailings are used because they hold an outstanding position in the discussion about tailings, as they are responsible for nearly half of the global volume of tailings (Baker et al., 2020).

1.0 TAILINGS LEACH PLANT, AN OVERVIEW From inception, Tailings Leach has been developed in three stages. The operation started with leaching of low-grade tailings using strong sulphuric acid followed by solution recovery and cementation of copper. The capacity then was about 1000 tonnes of copper per month.

Therefore, with an enrichment ratio of 56.70, the reduction in recovery is reasonable. Assessment of the recovery values of copper in the final molybdenum tailings (or final copper concentrate) also shows that a cleaner stage of flotation has resulted in a 10.0% increase in copper recovery to the final copper concentrate.
