摘要：
The fluorine distribution between SiF62– anions and aluminum, iron(III), and titanyl cations in sulfuric and nitric acid solutions containing phosphate ion depends on the kind of fluoride acceptor cation, solution acidity, composition of the acid solution, and reaction time. The data obtained allowed the development of an efficient technology for preparing nonradioactive rare earth concentrates by sulfuric acid leaching of phosphogypsum.
