Definitions

  • the present invention relates to the use of compositions of alkylammonium salts and amine alkoxylate esters in the flotation of silicate-containing minerals and ores.
  • Calcium carbonate is purified from silicate-containing and color-providing minerals with the aid of quaternary ammonium salts based on fatty acids or fatty alkylimidazoline compounds. Since calcium carbonate is used in addition to kaolin, rutile and talc as a white pigment in paper and plastic production, the highest possible whiteness or a low concentration of coloring minerals is desired. Due to the hardness of silicate, this would also lead to increased wear on the calenders of paper machines in papermaking. Therefore, calcium carbonate is purified in addition to dry processing via the flotation process.
  • the aim is to reduce the silicate content, which in the case of calcium carbonate is often characterized as an acid-insoluble constituent, by less than 1.0% by weight due to the reverse flotation.
  • the content of silicate in the task can vary and in some cases be from 10 to 20% by weight.
  • fatty amines, alkyl ether amines, alkyl ether diamines or quaternary ammonium salt compounds are used as silicate collectors. These are also known under the trade name Flotigam ®.
  • Flotigam ® In WO-A-00/62937 discloses the use of quaternary ammonium salts for flotation of iron ore.
  • EP-A-0 876 222 describes the use of biodegradable esterquats as a collector for the flotation of non-sulphidic ores.
  • 4,995,965 discloses the use of hydroxypropylated quaternary ammonium salts, unsymmetrically substituted dimethyldialkylammonium salts, and dialkylhexahydropyrimidine compounds as the collector in the reverse flotation of calcium carbonate.
  • CA-A-1 187 212 discloses quaternary ammonium salts and bis-imidazolines as collectors in silicate flotation.
  • U.S. 5,720,873 and EP 1 949 964 A1 disclose a collector for silicate flotation comprising an amine alkoxylate in addition to a quaternary ammonium compound.
  • PAPINI RM ET AL "Cationic flotation of iron ores: amine characterization and performance" MINERALS AND METALLURGICAL PROCESSING, CO, Vol. 18, No. 1, January 1, 2001 (2001-01-01), pages 5-9, ISSN : 0747-9182 discloses an overview of the cationic reverse flotation of iron ores.
  • the object of the present invention was therefore to provide an improved collector for the silicate flotation, which can be used in particular in the reverse flotation but also in the direct flotation.
  • a collector combination of an alkylammonium salt and an amine alkoxylate ester discharges less calcite fine grain than the previously described collector and collector combinations and thereby the recycling of valuable material is significantly improved, without thereby increasing the content of silicates in the concentrate.
  • Another object of the invention is a method for flotation of silicate-containing mineral by bringing a composition of A) and B) with the silicate-containing mineral in contact.

  • Example 1 Ground calcite, 100% ⁇ 250 microns, containing about 12 wt .-% silicate minerals, such as quartz, mica, and graphite, was transferred to a 2.5 L glass cell. The flotation pulp was then adjusted with drinking water to a level of 130 g solids per liter of pulp. The conditioning of the flotation pulp and the subsequent flotation was carried out with a DENVER flotation machine, type D-12. For flotation of the graphite, the flotation pulp was first conditioned with 20 g / t of a pine oil. The pine oil was added undiluted to the pulp and conditioned for 1 min. The graphite was floated in the foam phase (graphite flotation). The flotation time was completed after 3 min.
