摘要
This invention provides a process for the treatment of dust or sludge from a blast furnace, or from an electric furnace or converter of a steel works, to remove zinc therefrom, comprising continuously introducing the dust or sludge in a dried and crushed form into an iron bath, continuously introducing carbon- bearing material into the bath at the same time in an amount sufficient to maintain therein an amount of carbon which is greater than 1%, and adding to the bath slag-forming agent to form a slag of basic nature. A suitable installation for the purpose comprises a metallurgical container (10), a lance (23) provided with a refractory coating (26) and whose head (25) is disposed adjacent the bottom of the container and whose inlet is connected to a cell- type metering supply means (20) disposed outside of the container, and a discharge conduit (14) which extends within the container and which is connected to a dust collecting means (30).
