Description
| - Two sites in the semiarid Otavi Mountain Land in NE Namibia have been investigated. At Berg Aukas, Vrich mine tailings are >30 y old, but most V remains in primary descloizite embedded in carbonate matrix. Released V was incorporated into ferric hydroxides later transformed to hematite. In contrast, released Zn and Pb were incorporated into smithsonite and cerussite, which are less stable from environmental viewpoint. At Kombat mine tailings, As released from pyrite was also incorporated into hematite, but Cu from dissolution of chalcopyrite and bornite precipitated as malachite and cerussite, which are also much less stable than hematite. It seems that formation of hematite, which is relatively fast in tropical climate conditions, is favourable for attenuation of contaminants released into pore water.
