FIELD: nonferrous metallurgy. SUBSTANCE: invention is dealing with waste red slimes from silica production, worked out smelts from titanium chlorinator, etc. and is distinguished with that additional concentration of scandium from acidified carbonate eluate is achieved by bringing the latter in contact with semipermeable membrane, its pores being impregnated with liquid extract and on the other side of which mineral acid solution is circulating. EFFECT: increased degree of scandium isolation into concentrate, improved quality of concentrate, and simplified procedure. |
