Dust is used instead of the zinc shavings formerly employed on account of the large surface area made available. The method is based on the fact that gold and silver are electronegative to zinc and that the following reaction occurs in the precipitation process. KAu (CN)2 + 2KCN + Au + H2O = K2Zn (CN)4 + Au + H + KOH.

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.
