Sulfuric Acid Technology for Processing of Eudialyte Concentrate

  • V. N. Lebedev

Abstract

Sulfuric acid decomposition of eudialyte was studied, and a technological process including two-stage treatment with sulfuric acid, separation and washing of an insoluble residue, successive hydrolytic precipitation of zirconium and iron-manganese concentrates from solution, and recovery of rare-earth elements from the insoluble residue by leaching, was considered. It was found that zirconium(IV) is recovered from a complex carbonate precipitate in the form of a basic sulfate.
