• Iron, Cobalt, Copper, Nickel, and Zinc Introduction to

    Zinc is used in alloys with copper to create a harder metal known as brass. In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from rust. Cobalt and nickel are trace elements with properties similar to iron.

    Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for

  • The concentration of vanadium, chromium, iron, cobalt

    The copper range is the narrowest, and the cobalt range is comparable to that of nickel. Since in most cases concentrations of vanadium, zinc, and arsenic lie below the respective detection limits, the effective concentration ranges for these elements may be as broad as, if not broader than, the ranges for the other elements.
