摘要：
It was suggested to purify poor lanthanide concentrate precipitated from the extraction orthophosphoric acid produced by the dihydrate process to remove phosphorus and fluorine compounds by heating a mixture of the concentrate with sulfuric acid in the presence of hydrated silica followed by water leaching of water-soluble sulfates and phosphates. The treatment conditions for the separation of the bulk of phosphorus( V) and the entire fluorine in the form of SiF(4) were determined, ensuring approximately 3.5-fold increase in lanthanide concentration.
