How to extract zinc oxide from dust ash
The zinc oxide and the acid or base in the dust ash are reacted with the raw material, and then zinc carbonate or zinc hydroxide is precipitated. After filtration, washing, drying and calcination at 800 ° C, a high-purity light zinc oxide having a particle diameter of 1 to 100 nm is finally obtained.
