Abstract

Abstract

Pre-separation test of grinding-high intensity magnetic separation-medium magnetic separation was carried out on the flotation tailings of Gongchangling hematite. The iron grade of magnetic separation rough concentrate obtained by pre-separation is 41.71%, yield is 33.62% and iron recovery is 84.21%. The effects of two flotation processes, flotation column and flotation machine roughing, on the quality improvement of pre-concentration coarse concentrate were compared. The single factor test results show that the optimal working parameters of flotation column are feeding pressure 0.08 Mpa and aeration 0.05 m³/h. Through the closed-circuit test of one roughing, one cleaning and one scavenging process made of flotation column and two flotation units, the technical indexes of 18.89% concentrate mineral rate, 65.29% grade and 74.07% iron recovery can be obtained, which are 0.27 percentage points and 2.61 percentage points higher than that of single flotation machine process, respectively.
