· Mining operations degrade natural ecosystems by generating a large quantity of mine tailings. Mine tailings remain in dams/open ponds without further treatment after valuable metals such as iron ore have been extracted. Therefore, rehabilitation of tailings to mitigate the negative environmental impacts is of the utmost

· The insignificant effects of plant identity in this study could be related to the extreme soil conditions of the mine tailings pond, including the high acidity and heavy metal toxicity. Previous studies have shown the convergence responses of different plant species to heavy metal or other stressful factors (e.g. Meinzer, 2003 ).

Introduction. Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.
