Abstract

A process for the detoxication of waste slurries, in particular from the leather and skin industry, containing heavy metal salt complexes and organic materials comprises treating a suspension containing at most 100 kg/m<3> of solid material with sulphuric acid and/or a mineral acid mixture composed of at least 30% by weight of sulphuric acid. The acid liquid containing the heavy metal salts is separated from the slurry, and the solution is neutralized the metal salts are precipitated, purified and the organic slurry is washed to make it metal ion- and acid-free.
