Numerical Simulation of Gangue Adsorption and High Mineralization Ions Dynamic Migration Under Leaching Conditions
In response to the problem of low efficiency in purifying high mineralization mine water in the underground reservoir of Shicaocun Coal Mine,a numerical model of gangue leaching column is established using COMSOL numerical simulation software to explore the ion migration characteristics inside the leaching column under different particle size gradations,inlet concentrations,and inlet flow velocities.The results show that the larger the particle size gradation of gangue in the leaching column,the faster the migration speed of ions,the farther the migration distance,and the smaller the saturated total adsorption quantity of gangue;The higher the ion concentration at the inlet of the leaching column,the faster the migration speed of ions,the farther the migration distance,and the greater the saturated total adsorption quantity of gangue;The larger the inlet flow velocity of the leaching column,the faster the migration speed of ions,the farther the migration distance,and the larger the adsorption rate of gangue.However,the total adsorption quantity of gangue is the same under different inlet flow velocities.The research results are helpful for improving the efficiency of purifying high mineralization mine water in underground reservoirs.
