The Baotou complex iron ore is rich in rare-earth elements. The main rare-earth minerals are bastnaesite and monazite finely intergrown with fluorite, barite and iron minerals. The results of research into the flotation recovery of high-grade rare-earth concentrate from a bulk froth of salt minerals are described.
The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!

Iron is one of the most important strategic materials in national production, and the demand for iron ore is huge in the world. High quality iron ore reserves have been almost exhausted, and it is necessary to develop a technology that utilizes low-grade iron ore. Limonite is a representative low-grade iron ore due to its complex mineral and elemental composition. …

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
