1310 73 2cas 25kg Solid Caustic Soda Alumina Production Industry
Product Description
Solid caustic soda, also known as sodium hydroxide (NaOH), is a white, crystalline compound that is highly caustic and corrosive. It is one of the most widely used industrial chemicals and has a broad range of applications across various industries.
The solid form of solid caustic soda is typically available as flakes, pellets, or granules. Its physical appearance can vary depending on the manufacturing process and intended use. Solid caustic soda is highly soluble in water, and when dissolved, it forms a strong alkaline solution.
Solid caustic soda is produced through a process called the chlor-alkali process, which involves the electrolysis of a sodium chloride (NaCl) solution. This process simultaneously produces chlorine gas (Cl2), hydrogen gas (H2), and sodium hydroxide.

Application In Alumina Production Industry
In the alumina production industry, solid caustic soda (sodium hydroxide) is used in the Bayer process, which is the primary method for extracting alumina from bauxite ore. The Bayer process involves several steps:
Digestion: Bauxite ore is crushed and mixed with a hot caustic soda solution (sodium hydroxide) in large tanks called digesters. The caustic soda dissolves the aluminum-containing minerals in the bauxite, forming a sodium aluminate solution.
Clarification: The sodium aluminate solution is then clarified to remove impurities and solid particles. Solid caustic soda is added to the solution to adjust the pH and facilitate the precipitation of impurities.
Precipitation: Aluminum hydroxide is precipitated from the sodium aluminate solution by lowering the temperature and adjusting the pH. Solid caustic soda is used to maintain the alkaline conditions required for precipitation.
Calcination: The precipitated aluminum hydroxide is then calcined (heated) to produce alumina (aluminum oxide). The calcination process involves heating the precipitate to high temperatures to remove water and convert it into alumina.
Solid caustic soda is crucial in the alumina production industry as it helps dissolve the aluminum minerals in bauxite, facilitate the precipitation of impurities, and maintain the alkaline conditions required for the Bayer process. It plays a vital role in the extraction of alumina, which is a key intermediate in the production of aluminum.
