The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (Cmatter). In this study, the effect of MIBC on Cmatter flotation was investigated to understand the role of the frother in bubble and froth
