As a typical zinc oxide mineral, smithsonite has been developed as alternative sources of zinc metal to satisfy future demands with the gradual depletion of nature zinc sulfide ores. Restricted to inferior ability of floating, Zinc oxide is one well-known refractory zinc resource mineral with poor selectivity and high regent consumption.In this paper, ethylenediamine(NH2CH2CH2NH2) was selected to active flotation of smithsonite. The relationship of dosage of ethylenediamine and flotation efficiency was conducted, the results showed that the optimum dosage of ethylenediamine was 6×10-3 mol/L and flotation recovery could be reached to 95% when using dodecylamine-hydrochloride (5×10-4mol/L) as collector.this finding may have promote the recovery of refractory zinc oxide mineral resource.
