Applied Research Development of Flotation Column in Micro-Fine Hematite Flotation

Flotation column was originated from foreign countries, firstly it was mainly used in coal classification, then it has been used in nonferrous metal classification, due to the hematite iron ore resources tend to be poor, fine and complex, flotation column has the congenital advantage of micro fine minerals, therefore, this paper is according to the beneficiation technology of fine hematite ore in domestic and foreign ,through the characteristic of flotation column which is applicable to the processing of fine mineral, have good separation effect, and high enrichment ratio , flotation column are introduced in fine particle hematite beneficiation in some applications, Flotation column has a wide range of application prospects in our country fine mineral separation.
