Aluminium for Future Generations – Raw Materials
Bayer Process (alumina refining) Key input materials are the ores bauxite gibbsite (Al (OH) 3 ), boehmite (γAlO (OH)), or diaspore (αAlO (OH)), caustic soda (NaOH) and calcined lime (CaO) World average consumption of these inputs is outlined below: Raw Material kg per tonne of aluminaThe production of alumina from bauxite is a major enduse application for caustic soda Caustic soda is a basic feedstock in the manufacture of a wide range of chemicals It is used as an intermediate and a reactant in processes that produce solvents, plastics, synthetic fibres, bleach, adhesives, coatings, herbicides, dyes, inks and pharmaceuticalsCaustic Soda Prices, Markets Analysis ICIS2021 4 2 Thanks to its strong alkaline nature, caustic soda has an outstanding ability to dissolve or extract, making it the product of choice for applications in the pulp and paper industry, for alumina extraction from bauxite ore and for use in demanding cleaning applications, such as breweries, bakeries and other food processing environmentsCaustic Soda VynovaCaustic soda is a vital raw material used in almost every industry sector, which is why it is considered one of the true cornerstones of manufacturing Our caustic soda grades find key applications in the production of alumina and in pulp and paper productionInovyn Chlor AlkaliEGA receives first shipment of caustic soda in milestone for alumina refinery project Caustic soda and bauxite are the two most important raw materials of alumina refining EGA began importing bauxite in June Raw materials are initially required for commissioning – the process of testing and startingup individual pieces of equipment and sections of the plantEGA receives first shipment of caustic soda in milestone
