THE ULTIMATE GUIDE TO POTASSIUM CYANIDE VS SODIUM CYANIDE

Complementary to its reactivity toward acids, KOH attacks oxides. Therefore, SiO2 is attacked by KOH to present soluble potassium silicates. KOH reacts with carbon dioxide to give potassium bicarbonate:The "Expecting liquor" that contains these ions is separated with the solids, which might be discarded to some tailing pond or used heap, the recove
