Additionally, Lead (Pb) by-products are produced during the reduction of BZP, Pb volatilizes along with the fumes, resulting in secondary dust containing both zinc and lead. However, since the lead content in the raw materials used in this study is relatively low, this paper focuses primarily on the volatilization characteristics of zinc.
