Description
Here, "red mud, for recovery" refers to a strongly alkaline solid by-product generated and discharged when treating bauxite by the Bayer process during alumina production, appearing reddish-brown due to its high iron oxide content. Red mud mainly contains iron oxide, alumina, silica, calcium oxide, titanium oxide and small amounts of alkaline substances. After such red mud has lost its original process function or been discarded, following neutralization, dealkalization, stabilization and comprehensive utilization it can be used as a building-material raw material, metallurgical auxiliary material or for extracting valuable metals, achieving resource recovery.

Process Description
The "red mud for recycling" here refers to the strongly alkaline solid by-product produced and discharged when the Bayer process is used to process bauxite during the alumina production process. It is reddish-brown because it is rich in iron oxide. Red mud mainly contains iron oxide, aluminum oxide, silicon dioxide, calcium oxide, titanium oxide and a small amount of alkaline substances. After this type of red mud loses its original process utilization function or is discarded, it can be used as building materials, metallurgical auxiliary materials or used to extract valuable metals after neutralization, dealkalization, stabilization and comprehensive utilization to achieve resource utilization.
