Aluminium Sulphate Manufacturing Process
Bauxite mining: Bauxite, the primary source of aluminium, is extracted from open-pit mines.
Bauxite processing: Bauxite is processed to extract alumina (aluminium oxide) using the Bayer process, which involves crushing the bauxite and treating it with sodium hydroxide at high temperatures.
Calcination: Alumina is heated at high temperatures to remove moisture and convert it into aluminium oxide.
Reacting with sulfuric acid: Aluminium oxide reacts with sulfuric acid to produce aluminium sulphate and water:
Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O
Crystallization and drying: The resulting aluminium sulphate solution is cooled to allow the formation of solid crystals. The crystals are separated, washed, and dried to obtain the final aluminium sulphate product.
Granulation (optional): The dried aluminium sulphate crystals may undergo a granulation process to produce granules or pellets for easier handling.
The price of aluminium sulfate can vary depending on various factors such as the region, supplier, purity, quantity, and market conditions. Additionally, prices can fluctuate over time due to changes in raw material costs, production processes, and demand.

The chemical formula for aluminium sulfate is Al2(SO4)3.
Aluminum (Al): The symbol “Al” represents the element aluminum. Aluminum is a lightweight, silvery-white metal commonly used in various industries due to its excellent strength-to-weight ratio and corrosion resistance.
Sulfate (SO4): The symbol “SO4” represents the sulfate ion. It consists of one sulfur atom (S) bonded to four oxygen atoms (O). Sulfate ions are negatively charged and are commonly found in compounds such as sulfates, which are widely used in industrial and chemical processes.
Subscripts and Coefficients: The subscript “2” written after the Al indicates that there are two aluminum atoms in the formula. The coefficient “3” outside the parentheses indicates that the sulfate ion, Al2(SO4)3, is present three times in the compound.
