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 ...

Effect of the pulp potential on galena flotation with amyl xanthate as the collector [PDF]
REM: International Engineering Journal, 2023 The flotation mechanism of galena with xanthate as the collector is generally explained based on the mixed potential of the pulp, in which an anodic electron transfer reaction from the collector to the mineral is combined with an O2 cathodic reduction ...
