Abstract
The present invention is directed to provide a production method for carbonaceous material-containing metal oxide briquettes, capable of ensuring sufficient strength of briquettes while using a metal oxide material containing a large amount of fine particles, such as steel mill dust. This method comprises a mixing step of mixing a metal oxide material A containing a large amount of fine particles with a carbonaceous material B in a mixer, to form a powdery mixture E, a compacting step of compacting the powdery mixture E using a briquette machineto form compacts F, a classifying step of classifying the compacts F into an oversize fraction G and an undersize fraction H, using a sieve, and collecting the oversize fraction G as product briquettes, and a compact circulating step of returning a part of the compacts F to the mixeror the briquette machine, as a recycle material.
