The present invention relates to a method for manufacturing an iron powder from a forging scale comprising: a crushing and smashing step for crushing and smashing a forging scale by using a ball milling machine in order to make a power; and a reducing step for changing iron oxide to iron by reducing the crushed and smashed powder in a reduction method. According to the present invention, environment problems can be solved by increasing an added value since a forging scale which was disposed as waste materials is manufactured as an iron powder, and used as a material. Moreover, since gas generated in a process is steam, there are remarkable effects such as pollution-free, carbon-free, and an environment-friendly process. Moreover, since an iron powder is manufactured from a forging scale, there is an import-substituting effect. Since a material is immediately inserted as a base material in various industry fields, productivity and an added value are remarkably increased.
