Flotation of Iron Ores: A Review: Mineral Processing and

Nov 19, 2019A novel stepped flotation technique is discussed for the treatment of carbonate-rich iron ores. The necessity of desliming to enable effective flotation is discussed in detail. Selective flocculation desliming is discussed in particular detail as it is the primary deslime methodology used in industry.

Froth Flotation of Iron Ores

Jan 02, 2012In the iron ore industry, froth flotation is either used as a primary method for concentrating iron ores, such as Cleveland-Cliffs’ operations in Michigan, United States, or in combination with magnetic separation, which has become a popular practice in Minnesota, United States[1]. 2. Iron Ore Flotation Routes

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
