Effect of Mine Tailings on the Growth of Ornamental Plants

2021-6-4 · IV. CONCLUSION AND RECOMMENDATION The higher the amount of mine tailings added, the least the number of germinated seeds. Plant germination seemingly are restricted in mine tailings may due to the presence of different minerals particularly heavy metals, which usually in high concentration cause unfavorable growing conditions to seeds. The findings proved that further development of plant organs are affected or are influenced by soil minerals concentrations. In this case, it suggests that mine tailings …

Mine Tailings

Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.
