In order to improve the total copper recovery rate of Mirador copper mine, aiming at the

problems of high copper grade and large copper loss rate in the +75 μm fraction of roughing tailings, a new

Hydrofloat hydraulic flotation machine was used to investigate the effects of aeration rate of hydraulic flota⁃

tion machine, rising water flow rate, collector butyl xanthate dosage and foaming agent F-501 dosage on the

pre-enrichment effect of roughing tailings. The results show that flotation experiment carried out when aera⁃

tion rate is 0.85 m3 /min, rising water flow rate is 5 L/min, butyl xanthate dosage is 20 g/t, and F-501 dos⁃

age is 20 g/t, the rough concentrate with copper grade of 0.30% and recovery rate of 86.7% can be ob⁃

tained,which can provide reference for on-site process transformation.
