| titleOfInvention | Method of selective extraction of palladium, platinum and rhodium out of concentrates |
| abstract | FIELD: metallurgy. n SUBSTANCE: method consists in successive leaching and in dissolving each extracted metal: palladium - with solution of nitric acid, platinum - with mixture of nitric and hydrochloric acid and rhodium with solution containing hydrochloric acid; also each producing solution is removed. Notably, non-soluble residue with dissolved rhodium is subjected to leaching after dissolving of platinum; this leaching is carried out by dissolving sodium hypochlorite in solution of nitric acid diluted with water. All extracted metals are leached by bubbling reaction mass with air supplied via a porous partition from beneath. n EFFECT: simplification and essential saving of utilised chemical reagents; reduced time for separation and purification of metals. n 4 cl, 2 ex |
