On the Mechanisms of Silica (SiO2) Recovery in Magnetite ...

Dec 10, 2018  Magnetite (Fe 3 O 4) ore is concentrated by low-magnetic-field drums to recover a magnetite concentrate that is low in silica (SiO 2).The presence of SiO 2 in the magnetite concentrate for steel production increases the steel processing costs, so a major challenge in magnetic concentration is to lower the SiO 2 grade in the Fe concentrate. This work presents studies that were carried out on ...
