The low-grade copper sulfide mine tailings was found to be acidic with a pH of 4.5. Cation exchange capacity was determined to be 13.1 cmol/kg. The d 10, d 50, and d 90 values of the tailings particle sizes were 1.61, 16.18, and 72.4 μm, respectively. According to the particle size distribution results, it can be seen that the permeability of ...
