| Abstract: | Briefly introduced the ore properties of a lean hematite-limonite ore in North China.The influence of particle size of the grinding product and reagent dosage to flotation index were mainly studied.A reverse flotation closed circuit consisting of two-staged grinding,one middle-density magnetic and one high-density magnetic seperation to discard tailings,one roughing,one cleaning and three scavengings,separation middlings order to return could get the iron grade of 66.07% and iron recovery of 80.53%. |
