Iron ore beneficiation technologies
We offer a new technology from China, which can beneficiate low grades of hematite / limonite / goethite ores (including BHQ & BHJ) and also recover the left-over tailings from the conventional beneficiation plants, by converting them into magnetite ores, using the fluidised bed reduction-roasting method.
