Abstract
Results of investigations of the conversion methods of processing of large-scale fertilizer production of waste – phosphogypsum to ammonium sulfate and calcium carbonate (phosphomel). It is shown that, based on fosfomel can be synthesized by an innovative product multi-purpose – hydrocarboaluminates calcium 4CaO×Al2O3×nCO2×11H2O; the ways of effective use of hydrocarboaluminates calcium in the various sectors of the economy.
