A method is described for the removal of copper from copper‐rich effluents such as pot ale—a waste product from malt whisky distillation in copper stills. This method makes use of cementation on aluminium metal, obtained cheaply from aluminium beer cans, and could be of potential practical value for the detoxification of copper‐rich effluents such as pot ale and pig slurry before disposal to agricultural land. Traces of silver, gold and platinum have been found in pot ale by a spark source mass spectrographic technique which also uses a cementation procedure to pre‐concentrate trace elements on to aluminium metal.
