Obtaining nitrophos fertilizers with copper, zinc, molybdenum

The purpose of the research is to obtain micronutrient fertilizers by applying salts and their complex forms phosphorus obtained in incomplete standards nitric acid or salt mixtures. Central Kyzylkum phosphorites (low-grade P 2 O 5 -12.38%, CaO-43.68%, CO -13.48%, non-enriched -16.38%, CaO-45.93%, -18, 15%, SO 3 -1.86%, thermoconcentrate -27.40%; CaO-54.68%; - 4.52%) were decomposed with at different rates obtained. Copper zinc sulfate ammonium molybdate (Cu, Zn, Mo) applied chemical composition was studied. phosphorite flour processed concentrations acid. process granulation recycled carried out participation solutions, it possible fertilizers. Along nitrogen, phosphorus, potassium fertilizers, demand for also increasing our republic. Currently, microfertilizers are used practice very small quantities. In production mineral use various wastes products non-ferrous metallurgy containing microelements, sour effluents, spent catalysts other types secondary one solutions microelement
