| Research Abstract |
To develop an efficient recovery process of valuable metals from molten fly ashes,chlorination behavior and chemical form changes of lead and sulfur with CaCO3, CaOand Fe were investigated. In the case of CaCO3 addition, removal extent of sulfur from mixed sample was achieved to 53.9 - 66.1% at 1073 K, and lead sulfurization wassuppressed. Metal sulfate (M : Na, K, Ca, Fe) were formed in solid phase by theaddition of CaCO3 and CaO.
