Definitions

  • the mineral industry is a big consumer of chemicals. These are used in the various stages of transformation / modification / treatment that the mineral materials undergo. One of these steps is the dry milling of mineral materials, of which natural calcium carbonate is a prime example because of its many uses.
  • grinding aid agents, the function of which is to facilitate the mechanical action of grinding as described above. Introduced during the grinding step, they are found in the selection step. They are presented in a very general way in the documents “Calcium Carbonate” (Birkberger Verlag, 2001) and “Beitrag mentally Auf Kunststoffung derrowlect von Mahlosstoffn” (Freiberger Anlagenshefte, VEB Deutscher Verlag fur Grundstoffindustrie, Leipzig, Germany, 1975).
  • the prior art is particularly rich with regard to such additives, which can be classified into 3 categories: weak Bronstedt acids, weak Brontstedt bases and Lewis bases.
  • the first group dedicated to weak acids of Brônstedt contains, in particular, the formic, acetic, lactic, lignitic, adipic, lactic acid, fatty acids and in particular palmitic and stearic acids, but also certain salts of these acids such as lignin sulphonate salts. Illustrations are found in WO 2005/063399 and FR 2 203 670.
  • the second group consists of the weak Brönstedt bases; it includes in particular alkanolamines, including TIPA (tri isopropanol amine) and TEA (tri ethanol amine) well known to those skilled in the art.

  • Specific grinding energy refers to the total amount of energy expressed in kWh and necessary to grind a ton of dry calcium carbonate. Grinding capacity is the mass of dry calcium carbonate milled per hour.
