摘要：
It is shown that introduction of fluoride ions into recycled sulfuric acid solutions used for leaching of rare-earth elements from phosphogypsum precludes accumulation of thorium in these solutions, thereby making it possible to develop a technology for obtaining concentrates of rare-earth elements that rules out formation of intermediate and waste radioactive products.
