Currently, the mining sector has encountered problems related to off-grade copper deposits, while their demand in the global market has hiked . Hence, tailing dams are considered as a potential secondary source to meet the requirements. Falagan et al. stated that the past beneficiation techniques are less efficient in processing tailing.

"Increased focus on magnetite mining is one option. Magnetite iron ore is often more suitable and preferable for further processing and producing iron ore concentrate and pellets of DR-grade quality," says Basirat. "There may also be the possibility of beneficiation of some existing iron ore production towards DR-grade."
