It can also be found in limestones where ore ...Aug 11, 2018 · The sphalerite chemical formula is ZnS (zinc sulfide.) This chemical formula represents sphalerite in its pure form, but it is much more commonly found with significant amount of other elements substituting zinc. Up to 26 % Fe, 17 % Cd, 15 % Hg, 21 % Mn and small amounts of Cu, In, Ga, Ge and As may replace the zinc.
