Abstract:Having poor hydrophilicity, metallurgical dusts and sludge are difficult to recycle. Aiming at producing metallic briquettes for iron-making, investigations on agglomeration and reduction of metallurgical dusts and sludge are studied. Composite binder (CB) is used in agglomeration of the dusts and sludge. FT-IR spectrum indicates that CB contains a variety of active groups (-OH,-COOH). Using the wet-grinding process, CB dosage can be decreased to 1.4%. Composite binder has the role of catalytic reduction at high temperature. Compared to using bentonite briquettes, the iron content and metalliz
