METHOD FOR PRODUCING BRIQUETTES, METHOD FOR PRODUCING REDUCED METAL, AND METHOD FOR SEPARATING ZINC OR LEAD

摘要

Disclosed is a method for producing briquettes, by which briquettes having enhanced strength can be produced even when the amount of a binder used therefor is reduced as much as possible. Specifically disclosed is a method for producing briquettes, which comprises: a step of forming a primary granular material having an apparent density of 1,000-4,000 kg/m3 using a powder of metal oxides including iron oxide and one or more oxides selected from among zinc oxide, lead oxide and titanium oxide; and a step of forming a secondary granular material by compressing a plurality of primary granular materials, while having the primary granular materials contain one or more metal oxides selected from among zinc oxide, lead oxide and titanium oxide.
