    Introduction
  • Upcycling of mechanically treated silicate mine tailings

    The absorption was as high as 35% and 20% for alkali-activated HM and HA tailings, respectively, at 1 min of grinding time. However, there was a notable reduction in these values with further grinding of the tailings. It is important to note that water absorption was almost two times lower when the grinding time increased from 1 to 16 min.

    The word tailings is sometimes applied to include coarse mine waste. For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal.

  • Tailings Wikipedia

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
