摘要：
The leaching kinetics of magnesium slag in ammonium chloride solutions was investigated. The effects of initial ammonium chloride concentration, liquid-solid ratio and reaction temperature on the leaching rate of calcium were determined. The results showed that the leaching rate increased with the increase in initial ammonium chloride concentration, reaction temperature and liquid-solid ratio. It was determined that the leaching rate fit the Avrami equation, and the leaching process was controlled by diffusion. The activation energy was 13.22 kJ/mol.
