Technology of single and complex fertilizers: The monograph presents the results of phosphoric acid activation of all types of Central Kyzylkum phosphorites

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.
