Based on the iron ore processing experience and necessary processing tests, Prominer can supply complete processing plant combined with various processing technologies, such as gravity separation, magnetic separation, flotation, etc., to improve the grade of TFe of the concentrate and get the best yield.
In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore. In this chapter, the industrial practice and fundamental research activities of iron ore flotation are reviewed.
flotation cells. CPT Inc. has developed a flotation process for the production of Direct Reduction as well as Blast Furnace grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.
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.
This, of course, will vary with the nature of the ore. In one plant that employs gravitation previous to flotation the fine sand and slime only are treated at the rate of 50 tons per rougher. The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing cells and 4 cleaners.
3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore going to froth flotation cells for recovery of iron. 4.In magnetite processing plant,the process of flotation separation is replaced by magnetic separation.
