Aluminum Sulfate Preparation Method

Aluminum sulfate can be produced by reacting aluminum oxide or aluminum hydroxide with sulfuric acid. Kaolin is commonly used industrially to produce it. Low-iron aluminum sulfate lumps are a form of aluminum sulfate with a low iron content, typically less than 2×10-5%. Low-iron aluminum sulfate lumps are milky white solids with particle sizes ranging from 10 mm to 100 mm.
