The present paper deals with the treatment of phosphate obtained from a commercial sample of Akashat phosphate ore in hydrochloric acid. The factors studied are effects of the temperature of dissolution, acid concentration, and the time required for mixing phases. The experiments were performed with 100 kg/m3 of solid/liquid ratio, the size of the particles ranged 125-140 μm, the initial acid concentrations were 20, 30 and 40 wt% HCl, and the temperature of dissolution was kept constant at 30, 40, 50, 60 and 70 oC. The results indicated that the percentage of P2O5 increases as the HCl concentration increased using different time and temperatures. Also, the results showed that the best conditions for P2O5 recovery process according were acid concentration 40%, reaction time of 90 min, and temperature 30 oC.
