摘要：
A method of treating a plating sludge is disclosed, wherein a plating sludge, whose water content is decreased to not higher than 10% by weight, is mixed with scale, dust, both of which are formed in the alloy steel-making step, a binder and a carbonaceous material, and water is added to the mixture to adjust the water content of the mixture to 7-30% by weight, the mixture is kneaded and then molded into a briquet, and the briquet is subjected to a strength-improving treatment. The resulting briquet can be used as a raw material for ferroalloy. When the briquet is subjected to a reduction smelting to recover a metal, the metal can be used as a raw material for alloy steel.
