Formed metal-containing briquettes of high green strength, high shatter and good compressive strength in the cured state from a composition comprising a metal-containing waste, an aqueous solution comprising ammonium polyphosphate and magnesia. The product can be easily formed by mixing all components at room temperature, introducing the same into a mold and thereafter permitting the same to set. Setting is very rapid, and the product can be handled within minutes after molding. The product finds particular use as a replacement in whole or in part for metal sources in a steel-making process; it has the excellent advantages that the metal content thereof is extremely high and it introduces no harmful impurities into steel during steel making.
