WebRed mud as the main byproduct generated during alumina extraction from bauxite. Owing to the high iron content in the red mud and the high correlation between iron and … Webother acids, but the dissolution of iron was high as well (~60%). The maximum extraction of the REEs was around 80%. Sodium and calcium were completely dissolved during leaching. Dissolution of aluminium, silicon and titanium was between 30 and 50%. The leaching data show a very close association of scandium with the iron oxide phases. WebFeb 1, 2024 · High content of iron in red mud is the main hindering factor for the extraction of REEs from the solutions obtained by red mud acid leaching [28,29]. For this reason, the most promising way for comprehensive recycling of red mud is combined pyro- and hydrometallurgical methods with a recovery of iron by pyrometallurgical methods fol- oracle dba_high_water_mark_statistics
