Abstract

Abstract:

In order to effectively recover calcium and magnesium from phosphorus tailings after flotation in a phosphating plant,which can be used for the preparation of a new type of soil regulator,sugar alcohol chelated calcium-magnesium.The calcining and leaching kinetics experiment of phosphorus tailings was carried out.Based on thermogravimetric analysis and acid leaching rate of calcium and magnesium,the results showed that the thermal decomposition process of dolomite in phosphorus tailings was endothermic reaction,the thermal decomposition of dolomite followed the two-dimensional phase interface reaction model.The apparent activation energies of calcium and magnesium leaching reaction were 13.157 kJ/mol and 23.023 kJ/mol,the leaching rate was controlled by internal diffusion.And the kinetic equations of the thermal decomposition of dolomite and the leaching of calcium and magnesium were obtained.

Key words: phosphorus tailings, calcination, leaching, kinetics
