International Journal of Mining Science and Technology, 2022 In present study, a novel organic depressant N-thiourea-maleamic acid (TMA) was synthesized and applied as a galena depressant in the flotation separation of Mo-Pb ores. The depression behaviors of TMA were tested through flotation experiments.

Flotation behaviors of chalcopyrite and galena using ferrate (VI) as a depressant
International Journal of Mining Science and Technology, 2023 This paper investigated the effects of potassium ferrate (PF) on the flotation performances of chalcopyrite and galena. The flotation results showed that PF obviously depressed galena, but had little effects on the floatability of chalcopyrite within pH ...
