  • Zinc to Shine from Two-Year Doldrums [View article]
    thanks for an interesting summary.

    zinc (and copper, nickel) is found in nature as sulfide ores. zinc sulfide ores require roasting & then SO2 must be removed from the smelter offgas to avoid harm to the environment.

    zinc is an important trace element in plant & animal nutrition.

    a possible emerging use of zinc (as ferrite or titanate compounds) is for hydrogen-sulfide removal from coal-gasifier product gas, if the bugs can be worked out.
