Flotation of Iron Ores: A Review

A tremendous amount of research has been done on refining the flotation process for iron ore and designing the reagents which go into it. This paper reviews the industrial practices and fundamental research surrounding iron ore flotation. The advantages and disadvantages of direct flotation, cationic reverse flotation, and anionic reverse flotation are reviewed. A novel stepped flotation technique is discussed for the treatment of carbonate-rich...
