METHOD OF PRODUCING SCANDIUM CONCENTRATE FROM SCANDIUM-BEARING SOLUTION Russian patent published in 2017 - IPC C22B59/00 C22B3/24 C22B3/26 

FIELD: metallurgy.

SUBSTANCE: invention relates to chemistry and metallurgy, more specifically to technology of extracting scandium from product solutions, formed when processing uranium ore, during their production by underground leaching. Method of extracting scandium from scandium-bearing product solution uses an ionite with phosphorus and sulpho-containing functional groups, having high capacity for scandium. Operation of washing reduces costs for further processing desorption solutions and obtaining richer concentrates of scandium. Processing of acidified desorption solution before deposition of scandium concentrate by passing through high-basic anionite allows separation of scandium from uranium ions, which results in more efficient subsequent processing of desorption solutions to obtain concentrates richer in scandium and simplification of further production of scandium oxide.

EFFECT: technical result of claimed invention is obtaining more pure scandium concentrate.
