Study on the Leaching of Sodium Nitrate from Nitratine

Abstract:

The technology on the leaching process of sodium nitrate from nitratine was developed in this work. The effects of leaching duration, solid-to-liquid ratio on the leaching were studied. The results show that the utilizable sodium nitrate leaching ratio from the nitratine reach 90.2%, for leaching duration of 15 minute and at the solid-to-liquid ratio of 1.0 g.g^-1. A new scheme of step-by-step spray is advanced, according to the result of leaching repeatedly, which increased the concentration of lixiviation up to 29.58%( 400g.L^-1) at 25°C. The results reported will be useful for leaching process design and control.
