Abstract

A method of collecting zinc from a zinc-containing substance in a shaft type smelting reduction furnace having an inlet area and an exit area and provided with a packed bed of a carbonaceous solid reducing agent and having upper and lower tuyeres, which comprises the steps of: injection a zinc-containing substance together with a flux through at least one of said upper tuyeres; generating a furnace gas comprising a dust mainly consisting of carbon and ash, and waste gas, containing Zn vapor, generating by combustion of a carbonaceous solid reducing agent into said furnace, contacting a liquid coolant with said furnace gas at said exit area of said furnace, thereby taking up zinc in said liquid coolant to form a slurry, while removing gases generated by combustion of said carbonaceous solid reducing agent, and processing said slurry and collecting said zinc.
