  • Process and device for separation of absorbent/floating material from product mixes by means of float/sink separation
    Publication number: 20040050805
    Abstract: Device and process for separation of absorbent/floating material from product mixes by means of float/sink separation with a float/sink separator which exhibits a separator tank filled with a liquid separating medium, in which context there are provided devices for generation of a surface flow in the separating medium, which propel the absorbent/floating material as a floating fraction from a pickup point of the product mix to an output point for the floating fraction, along the surface of the separating medium, at such a speed as to inhibit absorption of the separating medium.
    Type: Application
    Filed: September 18, 2003

  • Process and device for separation of wanted materials from product mixes which contain floating/absorbent material and metals with a ferromagnetic content
    Patent number: 6119866
    Abstract: Process and device for separation of wanted materials from product mixes which contain floating/absorbent material and metals having a ferromagnetic content, particularly from ink cartridges by means of the following steps: coarsely comminuting the product mix, separating the floating/absorbent material from the coarse fraction by means of float/sink separation, and separating metals having a ferromagnetic content from the sinking fraction by means of magnetic separation.
