Definitions

  • the present invention relates to a process for separating at least one hydrophobic substance from a mixture comprising said at least one hydrophobic substance and at least one hydrophilic substance, and the use of a solid, hydrophobic surface for separating at least one hydrophobic substance from the above-mentioned mixture.
  • the invention comprises the separation of hydrophobic metal compounds, for example metal sulfides from a mixture of these hydrophobic metal compounds and hydrophilic metal oxides for ore enrichment by means of a hydrophobic surface.
  • Flotation is a separation process in which water-dispersed or suspended substances are transported by adhering gas bubbles to the water surface where they are removed with a clearing device.
  • air is introduced into the flotation bath and finely distributed.
  • the hydrophobic particles, such as sulfidic ores, are difficult to wet with water and therefore adhere to the air bubbles. So these particles are carried by the air bubbles to the surface of the pool and can be skimmed off with the foam.
  • a disadvantage of this process is that the air bubbles often lose their ballast on the way up. So that a sufficient yield can be obtained at all, chemical additives, for example xanthates, are added, which are intended to subsequently hydrophobicize the ore particles more strongly.
  • the constant import in air is also associated with a high risk potential.
  • the above-mentioned disadvantage could be circumvented in the so-called magnetic flotation.
  • the sulfidic ore constituents are specifically coupled or coupled to magnetic particles in this method.
  • a magnetic field is applied and the magnetic constituents containing the desired ore constituents are thus separated from the non-magnetic constituents.
  • US 4,657,666 a method for the enrichment of ores, in which the hydrophobic magnetic particle adheres specifically to the hydrophobic, sulfidic ore.
  • the magnetic particle is selected from magnetite or other magnetic iron oxides previously hydrophobized by attachment to silanes.

  • US 4,906,382 discloses a process for the enrichment of sulfidic ores in which they are stirred with magnetic pigments modified with bifunctional molecules.
  • One of the two functional groups adheres to the magnetic core.
  • the magnetic particles can be reversibly agglomerated by varying the pH.
  • the magnetic particles can be used to concentrate sulfide ores.
  • DE 195 14 515 discloses a method to concentrate recyclables with magnetite or hematite particles.
  • the magnetite or hematite particles are modified with carboxylic acids or functionalized alkanols.
  • SU-A-544464 discloses a method for separating magnetic and non-magnetic portions by passing this mixture past a rotating induction roller from which the magnetic portions are attracted.
  • a disadvantage of the methods for ore enrichment described in the prior art is that high magnetic fields are required to efficiently separate the magnetized particles from the original mixture. For this complex, expensive devices are necessary. Furthermore, it must be ensured that the magnetic particle coupled to the ore remains stably connected during the flotation process and can be effectively separated again after the separation.
