Salt and Marine Chemicals
Application Uses

Sulphate of Potash (SOP)

  • SOP is a premium two nutrient fertilizer (50% K2O and 18% S) with the highest total nutrient value (68%) and the lowest salt index (46.1).
  • SOP (K2SO4) offers an advantage over MOP (KCl) currently used by farmers with special focus on chloride sensitive crops, Dryland agriculture, sulphur responsive crops, drip irrigation and areas deficient in K & S.

Ultra Pure Magnesia

  • Ultra-pure magnesia is used in refractory lining for primary steelmaking as well as in magnesium metal production.
Salient Technical Features
  • No floatation is used for NaCl separation and recycle system designed leaches away NaCl with simultaneous increase in potash recovery.
  • The sea bittern and many of subsoil bitterns in the country are sulphate rich and hence the potash is recovered in form of SOP which is agronomically better fertilizer
  • The recovery/yield of potash is high because of integration and recycle of intermediate streams
  • The unit operations used are simple and most of the operations are carried out at ambient temperature except drying and calcinations of magnesium hydroxide to form MgO
  • The technology developed is environmentally benign.
  • There is no fear of IPR infringement in view of the strong patent position.
