Applications:
Soda Ash is mostly used as an ingredient in the manufacture of dyes and colouring agents, synthetic detergents and fertilizers.
It is used to improve and treat the alkalinity of lakes that have been affected by rain. It is used to reduce the acidity of emissions being generated from a power plant.
It is used in the manufacturing of household detergents. Many other organic products such as dishwashing soaps also contain varying amounts of soda ash in their formulations.
It is used in the manufacturing of glass, since it helps to reduce silica’s melting point. It is used in the recycling of aluminium and zinc.
It is used in the production of chemicals such as sodium silicate, sodium bicarbonate and percarbonate, sodium chromate and dichromate.
It is used in the manufacture of glues, preparing pulp and paper manufacture, and in soil preparation as well.
