Iron Concentrate Particles
Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use.
