Types of Iron Ore: Hematite vs. Magnetite_SMM

2013-9-6  Iron ore consists of rocks and minerals from which iron can be extracted. Ore is most often found in the form of hematite and magnetite, though goethite, limonite and siderite types are also common. Approximately 98 percent of the iron ore produced in the world is used to make steel. Hematite

Upgrading of Iron Concentrate by Fluidized-Bed

2019-3-6  Efficient use of abundant low-grade siderite ores can potentially mitigate the shortage of iron ore in the iron and steel industry in China. In this work, the beneficiation of siderite fines containing high levels of carbonates was studied using a combined fluidized-bed magnetizing roasting process. The siderite was almost completely converted into magnetite under the optimum conditions of ...
