Jun 01, 2021 As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.
iron processing - iron processing - Ores Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
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.
