Fluxed iron ore pellets
A product made from iron ore concentrate and fluxed in order to maintain target basicity.
The physical properties and chemical composition of iron ore pellets make them ideally suited for blast furnace production.
Fluxed iron ore pellets made from concentrate with Fe content over 69.5% can be used in direct reduction iron processes, with or without subsequent briquetting.
The final dimensions and characteristics are agreed with the customer individually
