Popis: In the paper the problem of utilization of stale hydroxide sludges containing non-ferrous metals and arsenic is considered. It is proposed to carry out two-stage leaching of sludges by solutions of complexing agents with recovery of 97-99% of non-ferrous metals to solution and removal of arsenic in the form of sparingly soluble compounds suitable for burial.
