There is two type of phosphate minerals for phosphate basic materials. Features of the apatite and the phosphorite deposits are given consideration. It is marked, that stacking process is forming from two sorts of phosphogypsum: dehydrate and semi-hydrate calcium sulphite. The results of studying the phosphogypsums' physical-mechanical properties are given. Specific structurial-mechanical, strength and strain conditions are considered.
