Flotation behavior of monoclinic pyrrhotite on different collector systems
Pyrrhotite often exists in an associated form in various nonferrous metal sulfide deposits.Identifying its flotation behavior can help improve the flotation separation of nonferrous metal sulfide ores containing pyrrhotite.The flotation behavior of monoclinic pyrrhotite was studied with monomineral flotation tests on the ammonium dibutyl dithiophosphate collector system and sodium diethyl dithiocarbamate.The results indicate that,compared with sodium diethyl dithiocarbamate,ammonium dibutyl dithiophosphate has a better collecting effect on monoclinic pyrrhotite.In the sodium diethyl dithiocarbamate system,using terpineol as a foamer can achieve higher flotation recovery of monoclinic pyrrhotite than methyl isobutyl carbinol(MIBC),while MIBC is more suitable for the ammonium dibutyl dithiophosphate system.NaOH only has a certain inhibition effect on monoclinic pyrrhotite in a strong alkaline pulp environment,while lime has a more significant inhibition effect on monoclinic pyrrhotite.Under the sodium diethyl dithiocarbamate system,the inhibition effect of lime on monoclinic pyrrhotite is more potent than that of the ammonium dibutyl dithiophosphate system.
