Studying the efficiency of an electroflotation process for the extraction of low-soluble scandium compounds from aqueous media in the presence of surfactants

Аннотация

The principal kinetic dependences of the electroflotation extraction of low-soluble scandium compounds from chloride, nitrate, sulfate, and carbonate electrolytes modeling scandium-containing feedstock leaching solutions have been studied. The role of surfactants of an anionic, cationic, and nonionic nature has been investigated depending on the composition of a background electrolyte. Under optimal conditions, scandium electroflotation extraction process was established to be efficient and the degree of extraction reached 97–99%.
