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.
