Magnetite ore stage grinding-magnetic separation process The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.

Iron Processing - FEECO International Inc.

Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
