摘要: A method for recovering zinc from substances containing a zinc compound which comprises supplying a carbonaceous substance and a zinc compound-containing substance onto the hearth layer in a sintering apparatus, vaporizing the zinc compound in said substance as metal to separate the compound therefrom by forming a locally strong reducing atmosphere at the combustion temperature of sintering material, oxidizing the resultant vapor-form zinc into zinc oxide under a strong oxidizing atmosphere, and then discharging the resultant zinc oxide as such from said sintering apparatus.
