ArticleAuthor Cheremisina O. V.
ArticleAuthorData Cheremisina O. V., phone: (812) 328-84-09
Abstract Semiproduction experimental plant on extraction of phosphates and fluorides of rare-earth metals is offered on the basis of the spent laboratory researches and semiindustrial tests at OJSC «Balakovsky chemical plant» on crystallisation of phosphates of rare-earth metals from industrial technological solutions. Process flow diagram of installation on their extraction is developed for crystallization process stage of rare-earth metals. The columnar crystallizer is developed, its description and the design is resulted.
keywords Apatite concentrate, rare-earth elements, crystallization, kinetic constant, energy of activation, solution of phosphoric acid, extraction.
