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.
  • silicate content which in the case of calcium carbonate is often characterized as an acid-insoluble constituent, below 1.0% by weight.
  • the content of silicate in the task can vary and in some cases be from 10 to 20% by weight.
