Definitions

  • WO 2007/008322 A1 discloses a magnetic particle, which is hydrophobized on the surface, for the separation of impurities from mineral substances by magnetic separation processes. According to WO 2007/008322 A1, a dispersant selected from sodium silicate, sodium polyacrylate or sodium hexametaphosphate can be added to the solution or dispersion.
  • Suitable oxidic metal compounds which can be used according to the invention are preferably selected from the group consisting of silicon dioxide SiO 2 , silicates, aluminosilicates, for example feldspars, for example albite Na (Si 3 Al) O 8 , mica, for example muscovite KAI 2 [(0H, F) 2 AISi 3 Oi 0 ], garnets (Mg, Ca, Fe ") 3 (Al, Fe"') 2 (Si0 4 ) 3 and other related minerals and mixtures thereof. Accordingly, ore mixtures which are obtained by treating mine deposits with conventional methods for separating the ores are preferably used in the process according to the invention.
  • tailings differ from conventional ores in mines in that the concentration of ores or precious metals in the tailings is significantly lower than in the original ores. Furthermore, the tailings may be present as fine-grained residues in the form of sludges, for example, the particles have diameters of 20 to 50 microns. But there may also be larger particles.
  • Tailings unlike ores obtained in mines, may also contain impurities in the form of organic compounds and / or salts, and may optionally have a pH that differs from the neutral pH of the original ores, ie acidic or basic Area is located.
  • Z is - (X) n -CS 2 " , - (X) n -PO 2 " or - (X) n -S " where X is O and n is O or 1 and a Kati
  • Most preferred surfactants are 1-octanethiol, potassium butyl xanthate, potassium octyl xanthate, octyl phosphonic acid or (octyl carbethoxy) thiocarbonyl ethoxy amine.
  • Potassium octylxanthate (IV) and (octylcarbethoxy-thiocarbonylethoxyamine (V) are shown below:
  • Y is selected from the group consisting of - (X) n -SiHaI 3 , - (X) n -SiHHaI 2 , - (X) n -SiH 2 Hal with HaI equal to F, Cl, Br, I, and anionic groups such as - (X) n -SiO 3 3 " , - (X) n -CO 2 " , - (X) n -PO 3 2 " , - (X) n -PO 2 S 2" , - (X) n -POS 2 2 " , - (X) n -PPS 3 2” , - (X) n -PPS 2 " , - (X) n -POS " , - (X) n -PO 2 " , - (X) n -CO 2 " , - (X) n -CS 2 " , - (X) n
