Chemicals

Approximately fifteen percent of soda ash production is used by the industry.

Soda ash is an acknowledged source of sodium ions. It also aides the solubility and reactivity of many inorganic compounds in water. As such, it is used as a major raw material for the economical production of sodium phosphates, sodium silicates, chrome chemicals and photographic chemicals. It is also used in the production of sodium bicarbonate (baking soda), which is an essential ingredient in the beverage, coatings, detergents, food, dialysis, and personal care markets.

For many of applications, ANSAC soda ash is interchangeable with caustic soda, while offering a cost advantage. Thus, it can be used as a functional substitute for caustic soda in many applications, such as:

  • pH adjustment/acid neutralization
  • Manufacturing of sodium chemicals including sodium phosphates, sodium sulfate, sodium sulfite, sodium acetate, sodium nitrite and sodium citrate
  • Kraft pulping
  • Flue gas desulfurization

Soda ash is also used as a raw material in the:

  • Production of various chemical fertilizers, such as synthetic sodium nitrates and fragmented phosphates
  • Production of artificial sodium bentonites or activated bentonites
  • Manufacture of synthetic detergents
  • Organic and inorganic coloring industry
  • Enamelling industry
  • Petroleum industry
  • Fats, glues and gelatine industry
