Paper Title:
Study on Microwave Pretreatment of Diaspore
  Abstract

The effects of microwave radiation pretreatment on the leaching behavior of diaspore were investigated. The influence of sodium hydroxide addition, microwave irradiation temperature and microwave irradiation time were studied, the mechanism of microwave roasting pretreatment was also studied. The results show that microwave roasting pretreatment can greatly improve the leaching efficiency of Al2O3, and decrease the mole fraction of digestion liquor. The optimal microwave roasting condition is that the sodium hydroxide addition is 100kg/t, the microwave irradiation temperature is 535°C, and the microwave irradiation time is 5min the roasting mechanical is that the increase of effective affecting acreage and the formation of high active alumina.
