Where Magnetic Iron Ore Is Used

The worlds resources are dominated by lowgrade ore though current world production of iron ore is largely by supply from deposits of highgrade ore composed of either rocks of massive hematite or pisolitic goethite World iron ore production in 2013 was 295 billion tonne with the major producers being China Australia and Brazil

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
