Chemical Composition Of Red Mud
Mineral Phase and Physical Properties of Red
Different characterizations were carried out on red mud uncalcined and samples calcined in the range of 100°C–1400°C. In the present paper, the phase composition and structural transition of red mud heated from room temperature are indicated by XRD, TG-DTA, and SEM techniques. The mean particle diameter, density, and bond strength of these samples also have been investigated.

US3776717A - Method for processing of red
The red mud by-product of aluminum manufacture is processed by first removing its alkali metal content by causticization of a slurry thereof with burnt lime in the presence of humic acid or derivative thereof. From the remaining solids iron can be recovered such as by reduction and smelting, where the humic acid-containing ingredient, a soft coal, can be utilized for its carbon content.

main chemical compositions in red mud, such as Ca, Al, Si, Na, and K were dispersive. Calcium was liable to concentrate highly in some larger size phases, while Al and Si were more dispersive. Na and K had a very similar distribution. As expected, Fe and Ti concentrated mainly in the some phases with granular shape. Thorium was not detected in the studied micro-zone, possibly due to the

24.02.2020· Composition of Mud. Mud is produced from a mixture of soil and water. The term "mud" isn't used unless the mixture is significantly thicker than pure water and has a slimy or sticky consistency, as shown in the photo above. The consistency depends on the contents of the soil as well as the amount of water that's been added.
