All Comments by john s. gordon »Zinc to Shine from Two-Year Doldrums [View article]
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.
