Chemical processes of phosphorites reduction by natural gas have been examined in the presence of sodium sulphate. The exchange of soda fluxing additives for sodium sulfate decreases the reduction process temperature, when such valuable products as phosphorus sulfides are formed, namely P4S10. We have shown that such exchange allows to reduce the process power consumption.
