Brief Description

Description :

In process under optimized condition, sulfuric acid leaches 98% Nd, 97% Fe, 60% Ni and 7.5% B from hard disk, after which selective precipitation of Nd and leaching of the precipitate with 5-20% HF solution was carried out. The Neodymium thus obtained is used in the scintillation detectors, magnets, laser materials, rare earth flouride crystal glass optical fibre,aviation magnesium alloy for metallurgic industry and also in electrolytic production of metal addictives.
