Market Needs
Lime is an essential chemical in the alumina production process. It is used for desilication, liquor purification, hydrate filtration, red mud management, and environmental control. Lime helps improve the efficiency and quality of alumina production while also mitigating environmental impacts.
Solution
In the alumina production process, lime is essential for various stages, with different types used for specific purposes. Quicklime (CaO) is primarily employed for desilication and liquor purification. Hydrated lime (Ca(OH)₂) is used for water treatment, while limestone (CaCO₃) aids in red mud management and environmental control, such as flue gas desulfurization. Each type of lime enhances the efficiency, quality, and sustainability of the alumina production process.
