    摘要: Apparatus for treating spent hydrochloric acid from a galvanizing pickling bath wherein the spent acid is neutralized with ammonium hydroxide and aerated to form a solution of ammonium chloride with suspended iron oxides and hydroxides. The ammonium chloride solution, freed of the magnetite, is usable as a recycle material in the galvanizing process.
