In this paper, the raw material is Polyhalite of Nongle, in Sichuan. This thesis presented the leaching mechanism and leaching behavior for leaching Polyhalite using leaching agent from the aspects of static state and dynamic state, which the lixiviant is CaCl2, and the paper introduced the fundamental kinetic theory for leaching behavior.
The static leaching experiment was studied in the paper, under the condition of different granularity, temperature, concentration of lixiviant, pro...
