Abstract

Conversion processes occurring upon introduction of various kinds of magnesium-containing raw materials in separate technological stages of fabrication of complex NP fertilizers based on ammonium phosphates and NPK fertilizers produced by acid decomposition of phosphate raw materials were studied. It was found that there occur exchange interaction processes yielding double magnesium-ammonium sulfates, magnesium hydroand dihydrophosphates, and double magnesium-ammonium hydrophosphate. The involvement of magnesium chlorides in the conversion processes is confirmed by the formation of polyhalite.
