Leaching of Sphalerite with Hydrogen Peroxide and Nitric Acid
Sphalerite is a polymorph with wurtzite and marttite. The three are called polymorphs (meaning many shapes) because although they have the same chemical composition, (Zn, Fe, and S as the major composition), they have different structures and therefore different shapes. Sphalerite is by far the more common mineral of the three [1].
