<p>A technology of recycling metals based on theories of corrosion and electroplating, for effectively utilizing scraps of metals, mainly iron, which poses social problems. All the three types (powdery, thin slide, and solid types) of metal scraps are treated at the same time only by the method of this invention to be recycled to highly value-added products, in which metal scraps are dissolved in acid solution and subjected to electrolysis so as to be recycled as metals of high purity. In this way, discarded scraps of metals are effectively utilized again, whereby recycling thereof is promoted.</p> |
