摘要： This method comprises a mixing step (90) in which a mixed processing material is obtained by mixing waste (7) and a reducing agent (8) with each other, a chlorine recovering step (91) in which chlorine and water are then recovered by heating the mixed processing material, a lead recovering step (92) in which fluorine and lead are then recovered by heating the mixed processing material under vacuum, a zinc recovering step (93) in which metal zinc is then recovered by reducing and evaporating zinc by heating the mixed processing material at a temperature higher than that in the lead recovering step (92) with the vacuum condition maintained, and a residue recovering step (94) in which the residue of the mixed processing material is then recovered. The method of this constitution enables high-purity metal zinc to be recovered from zinc oxide-containing waste, and such waste to be processed on site.

摘要： A treating method of recovering zinc in the metal state from a waste containing the zinc in the oxide state, lead, chlorine, fluorine, and water comprising a mixing process 90 of obtaining a to-be-treated mixed material 70 by mixing a steel dust 7 and a reducing material 8 together; a chlorine recovery process 91 of recovering the chlorine and the water by heating the to-be-treated mixed material 70; a lead recovery process 92 of recovering fluorine and lead by heating the to-be-treated mixed material 70 under vacuum; a zinc recovery process 93 of recovering metallic zinc by heating the to-be-treated mixed material 70 at a temperature higher than that in the lead recovery process 92 with the vacuum state maintained so as to reduce and vaporize zinc; and a residue recovery process 94 of recovering a residue 79 of the to-be-treated mixed material 70. This construction allows the metallic zinc to be recovered at a high purity from a zinc oxide-containing waste and an on-site treatment to be accomplished.
