neutralization. Neutralization consists of the addition of acid or base to adjust pH levels back to neutrality. Since lime is a base it is sometimes used in the neutralization of acid wastes. Coagulation consists of the addition of a chemical that, through a chemical reaction, forms an insoluble end

Introduction. ,Acid mine drainage, represents a major source of water contamination in regions of previous mining activity (McCarthy, 2010; Naicker et al., 2003).A number of processes are responsible for this contamination, most notably the weathering of waste piles and leaching of toxic ions through these piles into groundwater, or surface run-off of to surface water bodies ().
