Traditional and new methods of the production of ammonium sulphate and complex salts based on it are considered. The problem related to the sales of many wastes and by-products of metallurgical enterprises, in particular technical-grade ammonium sulphate formed in the by-product coking department of JSC ArcelorMittal Temirtau that could become the secondary raw material basis to manufacture marketable products, has not been solved yet. Alternative methods of obtaining ammonium sulphate from industrial, agricultural and animal farm wastes are presented, along with various areas of its application. Relevance of the production of complex salts based on ammonium sulphate and the possibility to increase its consumption in agriculture by obtaining complex salts with decreased acidity and increased content of useful components are demonstrated. The new possibilities of sulphate ammonium application and the potential of its application as a reagent for the production of anhydrous sodium carbonate and ammonium hydrofluoride are proposed.
