原始语种摘要: Yttrium belongs to the rare earth elements and critical metals. Yttrium oxide is mostly used in fluoroscent lamps, production of electrodes, in electronic filters, lasers, superconductors and as additives in various titanium-aluminium materials to improve their properties. Recovery of yttrium oxide from secondary sources such as red mud, coatings from ceramic industry and phosphors is extremely important. The main aim of this study is to examine the selective recovery of yttrium oxide from Al-Ti based secondary materials using one combined method based mostly on leaching for selective recovery of yttrium containing: crashing and grinding of materials, sieving, leaching of chosen fine fraction with hydrochloric acid, precipitation with oxalic acid in order to produce a pure yttrium...
