Ore has a crucial effect on water and tailings quality. Ore sorting targets to remove the non-valuable material in the beginning at a coarse particle size to avoid the processing of barren material below the cut-off grade, where the processing would cost more than the value of the metal (Duffy et al., 2015; Gülcan and Gülsoy, 2017).
