  • Zinc processing Britannica

    The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 °C (1,665 °F). Efficient methods of condensing the vapour to liquid metal were not discovered until the 14th century.

    However, since zinc, rather than cobalt, is preferentially retained by the resin, this process does not offer a practical method for purifying the zinc electrolytic solution"--Introduction, page 2-3. "The purpose of the present research is primarily to investigate the possibility of the separation and recovery of cobalt from zinc sulfate

  • Preventing Galvanic Corrosion

    For example, zinc-coated fasteners should only be used to connect steel coated with aluminum, zinc, and galvalume, as these are very close on the Galvanic Series and are not generally at risk of corrosion when placed together. On the other had, zinc-coated or aluminum-coated fasteners should not be used to attach copper or stainless-steel

  • Electrolytic Separation and Recovery in Caustic of Steel

    Abstract. Abstract. Experiments were conducted to examine the technical and economic feasibility of a single-step process for electrochemically separating and recovering in hot caustic the components of galvanized steel.

  • Zinc - Essential Chemical Industry

    The lead splash condenser sprays lead using a series of rotors. The resultant lead/zinc mixture is pumped from the condenser (at about 830 K) and cooled using water-cooled immersion coolers (to about 710 K). The lead/zinc mixture passes into a separation bath where the zinc floats to the surface and the lead returns to the condenser via an underflow.

  • Zinc: smelting, producing and classification-Metalpedia

    The purification process utilizes the cementation process to further purify the zinc. It uses zinc dust and steam to remove copper, cadmium, cobalt, and nickel, which would interfere with the electrolysis process.
