Iron Ore Gangue Prior To Benifizenithion

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 lowgrade iron ore limonite into a highgrade iron ore with low gangue content, low porosity, and high Fe and Fe2O3 content to enhance the sustainable development of iron and steel industries. The effects of the combined ...
