Pelletizing

LKAB has six pelletizing plants: three in Kiruna, two in Malmberget and one in Svappavaara. The total capacity of the plants amounts to approximately 28 million tonnes of processed iron ore products per year. The pellets are formed. In the pelletizing plant, a clay mineral, bentonite, is added as a binder in the iron ore concentrate.Get price
