Abstract
Phosphogypsum is an industrial waste of the processing of Khibiny apatite concentrate into chemical fertilizers by sulfurous technology. This is a valuable and promising technogenous rare-metal feedstock. The samples of fresh and old phosphogypsum were studied using precision physical techniques of analytical electron microscopy and X-ray spectral microanalysis. These studies allowed the discovery of new and unusual mineral compositions including strontium and rare earth metals in mineral fractions of phosphogypsum. The appearance of a new generation of technogenous rare-metal raw material permits us to characterize the prospects of its industrial use and to develop nonwaste technologies of its complex treatment.
