摘要: Black shales are sedimentary rocks containing> 0.5% of organic carbon. They host polymetallic deposits which have been mined for Cu, Ni, Zn, Mn, P, Mo, V, U, Au and PGE (platinum group elements). Even sub-economic occurrences provide potential risk of acid rock drainage when exposed to oxic surface environment. The natural acid neutralisation potential varies depending on the adjacent rock units, especially on the presence of calcareous rocks. The chemical and mineralogical composition of black shale is reflected in …
