Commercially available aluminum hydroxide is produced using the Bayer process, which involves dissolving bauxite in sodium hydroxide at temperatures of up to 270 C (518 F). The waste solid, bauxite tailings, is removed, and aluminum hydroxide is precipitated from the sodium aluminate solution that remains. Supplier Database:

Deposits of kaolin are located by drilling holes in the earth, which can range up to 200 feet in depth. When kaolin deposits are encountered, core samples of the deposits are extracted and sent to a laboratory for testing. Once mined, the crude kaolin is hauled to a stockpile, where the processing journey begins.

2016-10-27It has been shown that an electric spark discharge in saturated alkaline solution acts as a catalyst of ionization during the decomposition of kaolinite into aluminate and silicate components. The production of aluminum hydroxide from KM-1-grad kaolin (Chalgansk deposit) is 24.8–37.2% of the estimated value.
