Аннотация
The methods of nitric acid processing of phosphate raw materials are analyzed. A technology has been developed for the nitric acid processing of phosphate raw materials into nitrogen-phosphorus fertilizer with the implementation of the process in a condensed pulp by adding sulfuric acid. A technology for producing complex fertilizers with a wide range of N:P2O5:K2O ratios with improved physico-chemical parameters due to the introduction of various potassium salts into the process is proposed.
