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.
  • the separation of the substantially isolated magnetic particles from the ore particles and the other constituents of the concentrate stream is then equally within the "unload" process via a further or third separation device again typically in the form of or comprising a magnetic separator in which the magnetic particles magnetic be separated.

  • magnetic or magnetizable magnetic particles are fed to a pulp continuously flowing through a reactor, which form ore-magnetic particle agglomerates with the non-magnetic ore particles.
  • the ore magnetic particle agglomerates are moved by means of a magnetic field into an accumulation region of the reactor and removed from the accumulation region of the reactor.
  • the mass flow containing the first magnetic particle further comprises a certain proportion of ore particles and the mass flow containing the second ore particles furthermore has a certain proportion of magnetic particles. Accordingly, certain losses occur both with regard to the magnetic particles and the ore particles, since both the ore particles present in the first mass flow and the magnetic particles present in the second mass flow are not or only with considerable effort available for further use, which adversely affects the process yield effect. A detection of the composition of the corresponding first and second mass flow does not take place.

  • the information associated with the second mass flow is a measure of the proportion of magnetic particles in the second mass flow, which ideally contains only ore particles qualitatively or quantitatively determine the particular composition and a degree of pollution or a degree of purity of the respective mass flow.
  • the degree of contamination relates qualitatively or quantitatively to the proportion of unwanted particles contained in the respective mass flow; the degree of purity relates qualitatively or quantitatively to the proportion of desired particles contained in the respective mass flow.
