  2. Lead smelting - Wikipedia

    en.wikipedia.org/wiki/Lead_smelting

    Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.

  3. Electrolytic iron - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_iron

    As a result, iron is deposited on the surface of the cathode due to a difference in an ionization tendency, and high purity iron can be obtained. TOHO ZINC CO.,LTD. is producing and selling electrolytic iron refined by the wet process on an industrial scale. TOHO ZINC CO.,LTD. accounts for the top market share of high purity iron in wet type ...

  4. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system. Corrosion inhibitors such as sodium nitrite or sodium molybdate can be injected into these systems to reduce the galvanic potential. However, the application ...

    en.wikipedia.org/wiki/Electrochemical_machining

    B.R. and J.I. Lazarenko are also credited with proposing the use of electrolysis for metal removal. [2] Much research was done in the 1960s and 1970s, particularly in the gas turbine industry. The rise of EDM in the same period slowed ECM research in the West, although work continued behind the Iron Curtain. The original problems of poor ...

  7. Anodizing - Wikipedia

    en.wikipedia.org/wiki/Anodizing

    Carbon flakes or nodules in iron or steel with high carbon content (high-carbon steel, cast iron) may cause an electrolytic potential and interfere with coating or plating. Ferrous metals are commonly anodized electrolytically in nitric acid or by treatment with red fuming nitric acid to form hard black Iron(II,III) oxide. This oxide remains ...

    en.wikipedia.org/wiki/Conservation_and...

    Ferrous metals such as cast and wrought iron and steel usually corrode to form thick concretions that can entirely cover the metal object. [9] Corroded shipwreck artifacts that are made of iron may be conserved via electrolysis. Electrolysis is a method that uses an electric current to create a chemical reaction that cleans the object and ...
