rare earth scandium production process

Production Process of Scandium Oxide TRUNNANO

Scandium oxide is one of the more important products in scandium products. Its physical and chemical properties are similar to those of rare earth oxides, so the production methods are also very similar. Under certain external conditions, Sc2O3 can produce products of metal scandium salts and various scandium alloys.

Abstract: Baiyanobo ore is large iron, rare earth and niobium coexistence mineral deposit, and also contains scandium metal. Tailings are solid waste residue which formed during production processes of iron, rare-earths and niobium metals. A lot of emission and accumulation of the residues increase the cost of iron and rare earth production, and it also has brought
