A process is disclosed for the production of free-flowing, non-caking, stable granular ammonium sulphate containing micronutrients comprising granulating ammonium sulphate in the presence of a granulating aid which is stripped zinc electrolyte derived from an electrolytic zinc operation. An effective amount of stripped zinc electrolyte is used to yield a final ammonium sulphate product containing about 0.4% to 1.3% by weight zinc, up to about 0.16% by weight magnesium and up to about 0.09% by weight manganese. The stripped zinc electrolyte, typically containing 20-25 g/L zinc, 2-4 g/L magnesium, 1-2 g/L manganese and sulphuric acid, may be added during reaction of ammonia and sulphuric acid prior to granulation. A free-flowing, non-caking, hard, ammonium sulphate granular fertilizer having a pH of about 2 to 7.5 as 10% solution, containing by weight 0.4% to 1.3% by weight zinc, up to about 0.16% by weight magnesium and up to about 0.09% by weight manganese is produced.
