Definitions

  • the present invention relates to the use of collectors in the flotative processing of sulfidic ores.
  • Air bubbles are created by injecting air into the aqueous flotation slurry, to which the hydrophobized mineral particles adhere and are carried away to the surface of the flotation slurry.
  • the floating mineral of value, called concentrate, is skimmed off, while gangue minerals remain in the cloudy.
  • Foamers are added to modify the foam formation.
  • Commercial foaming agents include, for example, alcohols, polypropylene glycols and their ethers and MIBC (methylisobutylcarbinol).
  • US 4,699,711 discloses a process for flotating sulfide minerals with preferably short chain alkyl substituted thionocarbamates.
  • WO-02/38277 discloses the use of mixtures of thionocarbamates and mercaptobenzothiazoles as collectors for the flotation of sulfidic ores, in particular copper ore, which is associated with molybdenum and gold.
  • GB-A-798 769 and US-A-4 178 235 describe the flotation of niobium minerals with 8-quinolinol and 5-hydroxyquinoline, respectively.
  • GB-A-826 827 describes, in addition to 8-quinolinol, alkyl-substituted 8-quinolinol derivatives for the flotation of niobium minerals.
  • 8-Quinolinol has a high affinity for metal ions and forms complexes with them, so-called oxinates. 8-Quinolinol is therefore also used as a precipitation reagent for various metal ions.
  • GB-A-887 469 describes a method of recovering 8-quinolinol after use.
  • pyrite-containing ores are flotatively processed at pH values below 10 using commercially available sulfidic collectors such as dialkyldithiophosphates, xanthates, dialkylxanthoformates or dialkylthionocarbamates, concentrates with relatively high pyrite concentrations are obtained. In comparison to xanthates and dithiophosphates, the dialkylthionocarbamates are already considered to be very selective towards pyrite.
  • lime is added to the flotation slurry, which causes the pH of the flotation slurry to increase to over 10, depending on the amount.
  • the amount of lime added varies between zero and several kg per ton of ore feed depending on the pyrite content.
  • the lime thus contributes significantly to the reagent costs of the flotation process. Reducing the amount of lime and lowering the pH to below 10 would not only contribute to reducing sulfur oxide emissions into the environment, but would also save reagent costs. It was an object of the present invention to find an improved type of collector for sulfidic ores, which gives better flotation results than prior art collectors. Another object of the invention is to reduce the required amounts of pH modifiers, in particular lime, which is used to raise the pH and to press pyrite.
  • the invention thus relates to a floral reagent for sulfidic ores, comprising at least one compound of the formula (1)
  • R 2 , R 3 , R 4 , R 5 , R 6 and R 7 are independently hydrogen or groups containing 1 to 15 carbon atoms or groups containing oxygen or nitrogen, and at least one further compound serving as a collector for sulfidic ores.
  • the sulfidic ore collector is a compound containing at least one sulfur atom directly attached to a carbon or phosphorus atom, and said carbon or phosphorus atom is bonded directly to at least one further sulfur atom or to a nitrogen atom or to an oxygen atom.
  • Another object of the invention is the use of the flotation reagent according to the invention for the flotation of sulfidic ores.
  • Another object of the invention is a process for the flotation of sulfidic ores by bringing the flotation reagent according to the invention into contact with the sulfidic ores.
  • Another object of the invention is the use of compounds of formula 1 as an additive to collectors for sulfidic ores.
  • the sulfidic ores are preferably copper-containing ores which have up to 90% by weight of pyritic fractions.
  • the flotation reagent according to the invention can be used in a wide pH range, for example 2 to 12, preferably 5 to 12, and becomes the aqueous turbidity in a concentration between preferably 0.001 and 1.0 kg / ton of crude ore is added.
  • the compounds of the formula (1) are those in which R 2 , R 3 , R 4 , R 5 , R 6 and R 7 independently of one another are H or d- to C 4 -alkyl, in particular all H mean.
  • the further collectors are such compounds, the structural units of the formulas
  • the further collectors are dithiophosphates of the formula (6) OR 8
  • R 8 and R 9 independently of one another for hydrocarbon radicals with 1 to 10
  • Carbon atoms in particular C to Cio-alkyl, C ⁇ C to 0 alkenyl, C 5 to C -
  • Alkyl d- to C -alkenyl, phenyl, benzyl or naphthyl, and
  • M + stands for a cation, in particular a metal ion or an ammonium ion.
  • the mixing ratio of the compounds of the formula 1 to the other collectors which are represented by the formulas 2 to 10 is preferably 0.1: 99.9 to 20:80, in particular 1:99 to 10:90.
  • Embodiment contains the flotation reagent according to the invention between 0.1 and 20 wt .-% 8-quinolinol.
  • the following table shows the flotative results of the collector according to the invention in comparison with the standard reagent.
  • Laboratory flotation tests were carried out on a Chilean copper ore.
  • An ethylthio-, o-isopropylthionocarbamate and a dosage of 14 g / t raw ore feed was used as standard reagent (comparative examples 4 to 6).
  • a commercial foamer (MIBC) was added at a dosage of 15 g / t ore feed.
  • the invention is illustrated in the examples (examples 1 to 3). It corresponds to 94.4% ethylthio, O-isopropylthionocarbamate with the addition of 5.6% 8-quinolinol.
  • the values obtained for the copper contents and the yield are average values from three individual flotations.
  • Table 1 Effectiveness of the collectors according to the invention compared to the prior art
