As the largest supplier of natural soda ash in Africa, Botash extracts carbonate-rich brine from beneath the surface of Sua Pan to produce light and dense soda ash for a variety of industrial uses.
Soda ash, which reduces the boiling point of silica, is a major component in glass manufacturing and has extensive application across a wide range of industries including detergents, paper, chemical and metal beneficiation (particularly chrome and vanadium).
Dense and light soda ash is produced at Sua Pan in northern Botswana where it is transported by road and rail to various countries in Southern Africa.
Dense soda ash plays a critical role in glass production and is used as a fluxing agent, lowering the melting point of pure silica.
Dense and light soda ash are present in a large number of chemical reactions which produce the organic or inorganic compounds that are, in turn, used in a range of applications. For example, soda ash is used to produce sodium silicates, which are used to produce chemicals such as silica.
Light soda ash is used as a binder in powdered, paste and soap detergents. It acts as a water softener and cleaning agent.
Soda ash is used in the beneficiation and processing of mineral ores and metals, and in the production of cobalt and steel.
A source of sodium, soda ash is also used to adjust pH levels.
Soda ash is used in the recycling of zinc, aluminium and lead from spent batteries.
As a food additive, soda ash is used to produce dyes and corn syrups, and in the manufacture of ethanol.
Soda ash acts as a cleaning agent, in refining and bleaching, and to adjust the pH level during the drying process.
