Lead oxide melting rotary kiln

Dec 15, 2021

Jun 19, 2017 compounds are volatilized with zinc: e.g. lead, cadmium, chlorine, fluorine, sodium and potassium. If needed, a further calcination of the zinc oxide produced can occur in a secondary rotary kiln at 1000 C to separate the zinc oxide from other elements increasing the product quality to above 90% ZnO, depending on the lead content
