| Abstract: | In the commercial tests for iron-increasing and silica-reduction of magnetite concentrates in Gongchangling Mineral Processing Plant of Anshan Steel Group,a flotation column,FCSMC,was used as the main equipment for reverse flotation.Adopting a flowsheet with one-stage of rougher and two stages of scavenger,a concentrate with a iron grade of 69.15% and a iron recovery of 95.81% was obtained,meanwhile,the SiO2 contents in the product was reduced to 4.40%.This simplified flowsheet shows stable performance,whic... |
