Two mine tailings in the Copperbelt have been studied (Figure 1): the Chambishi site, (Figure 2), representing old tailings (about 40 year) and the Mindolo site, (Figure 3), representing relatively young tailings less than 10 year old. Both mine tailings have similar composition and the principal difference is in their age.
