  • The Process To Beneficiate Magnetite Iron

Iron ore beneficiation: an overview

In addition to this, stringent environmental regulations involved in the opening of new mines and the problems involved in disposal of tailings (slimes), it is the need of the hour to effectively beneficiate low-grade iron ore to make it suitable for iron-making process. The iron ore industries of India are expected to bring new technologies to ...

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.
