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 (~-0.074 mm) going to froth flotation cells for recovery of iron. 4. In the magnetite processing plant, the process of flotation separation is replaced by magnetic separation.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fine ores resulting from the concentration process must be agglomerated for use in iron and steelmaking.
