Application
Aluminum sulfate hydrate serves as a versatile starch modifier and firming agent. Its primary purpose is to enhance the texture and firmness of pickles and vegetables during processing. Additionally, it acts as a processing aid in the production of baked goods, gelatins, and puddings. This compound, a white powder known for its high solubility in water, is produced through the reaction of kaolin or nepheline with sulfuric acid. Beyond its use in the food industry, aluminum sulfate hydrate is utilized in various industrial applications. It plays a significant role in non-metallic flotation processes and is an essential component in by-product molybdenum circuits, where it helps depress talc at a pH of 7. Furthermore, it aids in the suppression of talc during the treatment of talcous nickel ores when paired with carboxyl methyl cellulose. Aluminum salts, including this product, are effective in depressing minerals such as calcite, dolomite, and barite, making aluminum sulfate hydrate a valuable co-depressant in fluoride flotation procedures involving barite-containing ores.
