Production Of Liquid Alum Coagulant From Local Saudi Clays

patented to produce aluminum sulfate [8]. When kaolin was heated to 1100 – 1200oC for one hour, then boiling calcined kaolin with sulfuric acid of concentration 5 – 7 wt.% H2SO4 for one hour, alumina extraction was about 80% [9]. Leaching with sulfuric acid was practiced at 90oC and 10 – 20 % acid concentration [10]. Another patent reported 30 wt. % acid concentration as the
