  • Product - Samarco

    Samarco’s product is iron ore pellets, small agglomerations made from ultrafine iron particles generated from the beneficiation of ore. Pelletizing is the process of compression or molding of such particles, which results in a spherical product ranging from 8 to 18 mm. The pellets are mainly used for fueling the blast furnaces in steel mills. Due to a higher ore concentration, the pellets ...
