The ash leaching process begins with mixing the ESP ash with water. Non-process elements dissolve in the water, while the useful chemicals mostly remain as solid particles. The solids are separated with a centrifuge and returned to the mill. The solution is rich in Chloride and Potassium and is sent to wastewater treatment.

Chemical etching is typically done with acid. Acid etching describes the process of applying hydrochloric/muriatic or buffered phosphoric acid to a concrete slab, Once the acid has an adequate dwell time, water is then used to rinse off the slab. The acid removes contaminates, reduces the surface alkalinity, and roughens the surface.

It has long been known from medical science and industry that freshly fractured surfaces can become chemically active specifically silicon dioxide (such as quartz, glass or in silicates) can become oxidizing. This is seen as the formation of hydrogen peroxide (H 2 O 2) when activated surfaces are brought into contact with water (humidity).

Leaching. Oxides are leached with a sulfuric acid or sodium carbonate solvent, while sulfates can be leached with water or sulfuric acid. Ammonium hydroxide is used for native ores, carbonates, and sulfides, and sodium hydroxide is used for oxides. Cyanide solutions are a solvent for the precious metals, while a sodium chloride solution dissolves some chlorides.
