The ,limestone neutralization, system is limited by the concentration and the rate of dissolution of carbonate. The solubility product defines that the carbonate dissolution cannot exceed 4.9×10-9 N. Increasing the surface area of ,limestone, can optimize the rate of dissolution; however, it must be ground to a particle size of approximately -200 mesh to be effective.

Most NNP values ranged between 400 to 830 kg CaCO 3 /t, which is equivalent to approximately 40% to 80% the theoretical neutralization potential of calcite or pure limestone (1000 kg CaCO 3 /t) . The NPR ranged from 26 to over 399 (ratio not calculated for AP less than the detection limit) ( Table 2 ).

Constructed Wetlands for Treating Acid Mine Drainage

Soil, clay, and synthetic covers can be placed over the ,acid,-generating rock to reduce infiltration of air and water (Durkin & Herrmann 1994). These capping procedures are costly and not completely effective in stopping the interaction of water, air, and pyrite rock. Chemicals can be used that reduce bacteria that catalyze the ,acid,-generation of AMD
