摘要： The invention relates to a method for regenerating reaction lubricant residues containing acid organic lubricants refused and processed during cold forming and multivalent metal ions and phosphate ions, wherein said reaction lubricant residues undergo the following procedural steps: a) precipitating metal ions from the metal organic compounds by adding phosphoric acid and/or acid phosphoric acid esters; b) dissolving water-soluble impurities by adding water; c) separating the solids from the lubricant components and from the aqueous phases that are incompatible with the oily lubricant components, and whereby d) acid phosphoric acid esters for adjusting the free acid at a value of less than 10 points and for adjusting a total acidity point value of less than 70 is adjusted at a free acid. total acidity ratio having a value in the range of 0.15 to 0.5. The separation indicated in step c) preferably occurs by means of a centrifuge at 2,000 to 3,000 g, especially at 8,000 to 15,000 g.
