  • Process for electrolytic iron powder
    Patent number: 4134800
    Abstract: An improved process for producing electrolytic iron is primarily based on maintaining the electrolytic bath at a low concentration of ferrous sulfate ions in combination with a certain concentration of NH.sub.3 and pH in the electrolytic bath. The electrolytic iron chips produced in accordance with this process are much more friable. A substantial improvement is obtained in an efficient grinding of the chips to -100 mesh (Tyler Screen) and smaller.
