The Ammonoalunite Process for Production of

Abstract. The ammonoalunite process begins with two-stage sulfuric acid leaching of calcined kaolinitic clay. The clarified aluminum sulfate liquor is subjected to modest temperature autoclaving in the presence of ammonium ions to precipitate the ammonium analog of alunite, NH 4 Al 3 (SO 4) 2 (OH) 6, in a hydrolysis reaction regenerating most of the acid needed in the leach.
