Definitions

  • a flotation cell or a flotation reactor is an ore-containing pulp, i. essentially a suspension of water, ground rock (gangue) and ground ore fed.
  • the pulp is charged with magnetic particles, including, for example, magnetic particles in the form of magnetite, to form so-called ore particle magnetic particle agglomerates (so-called "load process").
  • magnetic particles including, for example, magnetic particles in the form of magnetite
  • ore particle magnetic particle agglomerates prior hydrophobing of both the ore particles and the magnetic particles is usually required.
  • the formation of the orbital particle magnetic particle agglomerates produced essentially by hydrophobic interactions or forces of attraction takes place by mixing the starting materials taking into account certain mixing parameters, such as shearing forces, time, temperature, etc.
  • Separation of the corresponding ore particle magnetic particle agglomerates from the pulp is carried out by means of a (first) separation device, typically in the form or comprising a magnetic separator, wherein the magnetic ore particle magnetic particle agglomerates discharged from the pulp and into a so-called concentrate stream, which contains substantially the ore particle magnetic particle agglomerates, minor amounts of gait and water, be transferred.
  • a separation device typically in the form or comprising a magnetic separator
  • the ore particle magnetic particle agglomerates are incorporated into their constituents, i. Ore particles and magnetic particles, split, so that they are unbound in the form of a mixture next to each other (so-called "unload” process).
  • the ore particle-magnetic particle agglomerates are separated by means of a further or second separation device via chemical processes through the use of appropriate chemicals such as solvents or the like.
