摘要

The main indicators obtained during large-scale tests of the technology for complex processing of phospho-semihydrate produced from apatite concentrate produced by JSC Apatit, developed at the I.V. Tananaev Institute of Chemistry and Technology of Rare Elements and Mineral Resources, Kola Scientific Center of the Russian Academy of Sciences, are reported. The achieved results (high extraction of rare earth metals into non-radioactive oxocarbonate concentrate, degree of purification of the gypsum product from harmful impurities) confirm the efficiency of the technology.
