Iron ore concentrate is an enriched product, which is manganese in the process of using iron ore and is used to produce pellets for blast furnaces and briquettes containing iron. Therefore, the injection of iron ore concentrate in furnaces through tuyeres (combined with powdered coal or independently) is considered for blast furnace production. Concentrates are non-toxic, non-flammable and non-explosive products. Concentrates are transported as bulk goods by rail or by sea.
