Arsenic Disposal Practices in the Metallurgical Industry

Flotation tailings usually contain residual arsenic bear-ing sulphides and these compounds may become soluble as a result of pH changes brought about by acid mine drainage (Kwong et al., 2000; Soprovich, 2000) or algal activity (Taschereau and Fytas, 2000). Kwong et al. (2000) observed elevated As concentrations in the pore water of
