OBTAINING SCANDIUM-CONTAINING CONCENTRATE AND FOLLOWING REMOVING THE SCANDIUM OXIDE OF HIGH PURITY Russian patent published in 2018 - IPC C22B59/00 C22B3/12 C22B3/20 C01F17/00

Abstract RU 2647398 C2

FIELD: technological processes.

SUBSTANCE: invention relates to a method for processing red mud while preparation of scandium-containing concentrate and scandium oxide in which carbonization leaching is conducted, sorption of scandium on phosphorus-containing ionite, desorption of scandium and precipitation of scandium concentrate. Content of Sc₂O₃ is not less than 15 % by weight (in dry basis), TiO₂ not more than 3 % by weight (in dry basis), ZrO₂ not more than 15 % by weight (in dry basis), and scandium in the concentrate is in the form of a mixture of hydroxide Sc(OH)₃ with a basic salt of ScOHCO₃×4H₂O. Preparation of high purity scandium oxide from said concentrate includes dissolving scandium-containing concentrate in sulfuric acid.

EFFECT: technical result is increased extraction rate of scandium from red mud and increased purity of the products obtained.
