Mineral IntroductionIntroduction of iron ore: In the natural world, iron is mainly present in the form of iron oxides, sulfides, iron-containing silicates and iron-containing carbonates. At present, there are mainly the following iron mineral raw materials that have great value for the steel industry: magnetite, mirror iron ore, and limonite.
Common Mineral Processing Methods2.Common processing method: magnetic separation, flotation, combined mine selection
