Abstract: Considering the superiority of solution mining and its application potentiality， the paper describes the reaction-diffusion and the evolution process of pore structure in ores fissure system in mineral leaching process.Through analyzing the current research progresses at home and abroad， it is pointed out that the reaction-diffusion has a close and interactive relationship with the evolution of pore structure.The present research findings can't be applied directly， so that some new ideas are raised to research such issue further.

Key words: Solution mining, Kinetics of reaction, Evolution of pore structure
