Technology of single and complex fertilizers

In the monograph it was studied that the process of phosphoric acid activation of all types of phosphorites of Central Kyzylkum: ordinary phosphorite flour washed concentrate thermal concentrate as well as such large-tonnage waste of Kyzylkum phosphorite plant such as mineralized mass and pulverized fraction depending on various parameters. The process of phosphorus-acid thermal decomposition of ordinary phosphate meal washed concentrate and thermal concentrate at different weight proportions of acid: phosphorus raw materials and temperatures from 140 to 300 ºС has been studied as well as the basic technological scheme of single phosphate fertilizers production has been developed.
