202411 · The froth flotation process is a complex physio-chemical process that is influenced by several parameters (Rajapakse et al., 2022) (Fig. 4). Mineralurgist operators monitor the flotation froth’s color and texture to determine the mineral types and assess the flotation performance (Aldrich et al., 2022, Farrokhpay, 2011). In this study, we ...
