Limonite Siderite Iron Ore Beneficiation

2021-4-6  Limonite. The limonite ore was the lowest in grade of all the limonitic ores investigated, with an iron content of 21.0 percent and an acid insoluble content of 53.5 percent. Like the other limonitic ores, it contained little ferrous iron,with only 3 percent of the total being in this reduced state.

Upgrading Low-Grade Iron Ore through Gangue Removal

In this study, a combination of alkali roasting and hydrothermal treatment is used as a method of gangue (Si, Al, and P) removal from iron ores as a means to upgrade low-grade iron ore (limonite) into a high-grade iron ore with low gangue content, low porosity, and high Fe and Fe 2 O 3 content to enhance the sustainable development of iron and steel industries.
