EasyMining´s Ash2Salt technology extracts pure potassium, sodium and calcium chloride from hazardous fly ash.

EasyMining’s patented Ash2Salt process can extract commercial salts from high chloride containing fly ashes. After washing, the ash residue can be landfilled without an exemption for high chloride contents or re-used as an industrial raw material.

The Ash2Salt process can extract commercial grade:

  • Potassium chloride (KCl)
  • Sodium chloride (NaCl)
  • Calcium chloride (CaCl2)
  • Aqueous ammonia solution (NH3) or ammonium sulfate ((NH4)2SO4)

Circular salt

Potassium, calcium chloride and sodium chloride - for all the three main salts produced by the Ash2Salt technology, the climate footprint is about one-tenth of traditional production.

How does it work?

In the Ash2Salt process, the fly ash is washed, and three commercial salts are extracted from the wash liquid: sodium chloride, potassium chloride, and calcium chloride.

Ash2Salt plant inaugurated

On April 21 2023, the world's first facility for recycling of commercial salts from fly ash generated from waste incineration was inaugurated.
