  • Mine Tailings Waste Leaching & Groundwater Contamination

    Data available from the literature reflect that metal-ore tailings are highly enriched in their metal content. Due to crushing and grinding of ore for milling purposes, the tailings also consist of small sized particles. On this basis, the character of tailings favors the rapid leaching of metals under certain conditions.
