Definitions

  • the invention relates to an apparatus and a method for magnetic separation of a fluid containing first particles to be separated from magnetic or magnetizable material and further comprising second particles of non-magnetic or non-magnetizable material.
  • Recyclable material particles are often particles of magnetic or magnetizable material, which are already contained in the ore, and / or particle agglomerates, which arise from non-magnetic value minerals and additionally added magnetic or magnetizable auxiliary particles in the ore production.
  • first particles of magnetic or magnetizable material are hereinafter understood not only already contained in the ore particles of magnetic or magnetizable material, but also such magnetically separable particle agglomerates comprising auxiliary particles.
  • the valuable material particles or agglomerates comprising the valuable material particles should be separated from non-valuable particles of non-magnetic or non-magnetizable material.
  • ore is a more or less fangled, metal-containing mineral or mineral mixture called.
  • the term "gait” is understood to mean accompanying materials which occur together with the ore minerals, such as quartz, calcite, dolomite, etc.
  • Particles of magnetic or magnetizable material already contained in the ore, such as copper, iron, etc. are generally bound to non-metallic particles. magnetic or non-magnetizable particles bound by gait and are to be separated from these.
  • the ore is usually crushed and conveyed to a device which carries out the separation of the valuable particles.
  • the crushed ore is usually fluidized.
  • the fluid formed is either a suspension in which the ore particles are dispersed in a liquid, or an aerosol in which the ore particles are dispersed in a gas.
  • Suspensions such as those produced in mining for the extraction of ores, for example, are also referred to as sludges.
  • the magnetic or magnetizable particle experiences a force which moves or holds it against other acting forces.
  • forces are, for example, gravity or hydrodynamic frictional forces in a flowing liquid medium.
  • the magnetic force acting on a magnetic or magnetizable particle in a magnetic induction B is proportional to a product of the magnetic induction B and the component of the gradient of the magnetic induction B in the direction of the magnetic induction B.
  • fluids are chemically pretreated in the form of suspensions.
  • non-magnetic valuable particles from ore in such a way that they can bind to additionally added magnetic or magnetizable auxiliary particles, such as magnetite, and can be separated magnetically together with them.
  • the surface of the non-magnetic material particles is selectively functionalized, in sulfidic ores, for example by means of suitable xanthates.
  • these functional layers can form stable bonds with one another and therefore form stable bonds to form stable particle agglomerates or magnetizable auxiliary particles and non-magnetic recyclable particles. These agglomerates can then be separated from a suspension like magnetizable individual particles.
  • Permanent magnets can be found, for example, in the widely used drum separators, where they, rotating in the drum, act on magnetic or magnetizable particles.
  • the DE 31 20 718 C1 discloses another drum magnetic separator for separating and sorting out magnetizable substances from a mixture containing magnetizable and non-magnetizable substances, wherein the magnetic system of the magnetic separator generates a traveling field.
  • electromagnets An application of electromagnets is known in particular from the so-called high-gradient magnetic separation, in which magnetizable structures, such as needles or cutting, form a grid in an electrically generated, often initially homogeneous, magnetic induction B.
  • the lattice structure generates a locally highly inhomogeneous magnetic induction B with pronounced gradients.
  • the DE 32 47 557 A1 describes a device for high-gradient magnetic separation of the finest magnetizable particles from a flowing medium.
  • a disadvantage of such high-gradient magnetic separators is that the magnetic induction B is often switched off and a backwashing process has to be carried out to remove the separated magnetic or magnetizable particles. A continuous operation is not possible. It has also proven to be disadvantageous for the operation of devices for magnetic separation when the magnetic induction B generating permanent magnets or electromagnets must be moved mechanically during the deposition process, since such devices are susceptible to interference.
  • a "first particle of magnetic or magnetizable material” is understood here and below to mean not only a particle of magnetic or magnetizable material already contained in the ore, but also a particle agglomerate which comprises at least one non-magnetic valuable particle and at least one functional particle Layers bound magnetic or magnetizable auxiliary particles is formed.
