  • Understand what are the tailings ponds Vale

    Feb 23, 2016 . Already used in some of our operations, natural moisture processing uses the ore's own moisture to remove impurities. Another major advantage of the technology is that it eliminates the need for tailings ponds. High grade ultrafine iron ore particles can be used to make products rather than discarded in.

  • Mines and environmental impact SGU

    Mining waste has different characteristics depending on the type of ore being mined. Our Swedish ores can be roughly divided into oxidic and sulphidic ores. The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefteå field in Västerbotten. However, Sweden's.

    Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material.
