28/10/2021 · Step 4 Digestion process. In the digestion process, the slurry is heated to 270℃ to form a sodium aluminate supersaturated solution or "pregnant liquor". A hot caustic soda (NaOH) solution can dissolve the aluminiumbearing minerals in the bauxite. There are two types of bauxite: gibbsite, böhmite and diaspore.
Great Lakes Minerals, LLC (GLM) is a leading producer of aluminabased minerals, including highquality calcined bauxite. Calcined bauxite is used globally for its antiskid and high friction properties to make roadways safer. It is a strong and highly durable material, which makes it ideal to prevent slips on factory floors and other surfaces.
The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day yearround. A smelter cannot easily be stopped and restarted. If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive ...
Bauxite contains the aluminumbearing minerals boehmite, gibbsite, and diaspore. To extract these minerals and the alumina in them, the bauxite must be ground up into small particles and dissolved in sodium hydroxide, a caustic liquid. Steam and pressure are applied during this digestion process.
