Iron ore is an important raw material for iron and steel production enterprises.After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals iron ore.It is the mineral aggregates that contain iron or iron compounds which can be used economically.Production process of iron ore.
Single weak magnetic iron ores mainly include hematite, siderite, limonite and hematite vitrinite siderite, etc.Due to its various kinds and the wide range of disseminated grain size, the extraction of weak magnetic iron ore is also relatively complex, such as gravity separation process, froth flotation process, strong magnetic separation.
