As a pre-treatment method of refractory gold ore, carbonaceous matter (C-matter) flotation was investigated with multi-stage flotation by rougher, scavenger, and cleaner stages. Different dosages of kerosene and MIBC (4-Methyl-2-pentanol) were applie

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 carbonaceou
