hematite flotation

Hematite

Abstract: 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.
