Efficient Release of Potassium from Illite by Additive-assisted Roasting and Its Kinetic Process
摘要
Abstract
The process of potassium release from illite was investigated by a flux method, and the effect of relevant factors on the rate of potassium release was discussed. The results show that calcium chloride additive has a great effect on the potassium release rate from illite and the potassium release rate is 95.84% under the optimum experimental conditions. Based on the dynamics analysis, the rate of potassium release process is controlled by an internal diffusion mode. The rate of potassium leaching of calcined slag is controlled by the surface chemical reaction.关键词
