Abstract


The research of the decomposition process algerian phosphorite of nitrogen acid depending on temperature, concentration, duration process. It has been shown, that optimal technological parameters of process is concentration of nitrogen acid 50-55% mas., temperature 55-60°С, duration process 30 minutes. Under optimum conditions in the presence 2-5% of nitrogen acid surplus against stoichiometric quantity is achieved the maximum degree of seizure Р2О5 – 92,45% mas.


Keywords


nitrogen acid processing of phosphates; degree of seizure; optimal technological parameters
