Abstract

A method for collecting and recovering suspended, precipitated and/or dissolved material in waste water from furnace gas purification facilities for metallurgical processes, characterized in that waste water is passed through one or plus filters consisting of carbonaceous material such as coal or cock, etc., after which carbon filters with precipitated and absorbed or adsorbed material are used as a reducing agent in metallurgical reduction processes.
