Ruling out accumulation of thorium in sulfuric acid solutions for leaching of phosphogypsum

Ruling out accumulation of thorium in sulfuric acid solutions for leaching of phosphogypsum 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

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.
