Title: Method for concentrating, separating and recovering rare earth metal
Inventor: KIMURA AKIRA
IPC: C22B3/44
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To improve recovery efficiency and cost effectiveness by subjecting metal oxides contg. trace scandium, such as tungsten, stannum and uranium refining residues, to acid exudation at and under a high temp and high pressure at the time of separating and recovering the scandium. SOLUTION: The oxides contg. the trace scandium of about 0.001 to 0.4wt.% are charged together with an inorg. acid into a pressure vessel where oxygen or air is blown to maintain an oxidative atmosphere. The oxides are then subjected to an agitation treatment at and under the high temp. and high pressure of 150 to 260 deg.C and 5 to 48kg/cm<2> , by which the scandium is selectively leached into the acidic soln. The acidity of the scandium-contg. liquid is thereafter adjusted to pH4 to 6 to concentrate and settle the scandium. The scandium is thus recovered. While the inorg. acid to be used may be any of sulfuric acid, hydrochloric acid and nitric acid, the sulfuric acid is more preferable in terms of the corrosiveness to the vessel. The acidity of the ordinary temp. leaching liquid after the treatment of pH1 is the target for the adequate amt. of use.  By such concentration and sepn., >=95% of the scandium may be leached.
