Franklinite is an oxide mineral belonging to the normal spinel subgroup's iron (Fe) series, with the formula ZnFe 3+ 2 O 4. As with another spinel member magnetite, both ferrous (2+) and ferric (3+) iron may be present in Franklinite samples.
Named in 1819 by Pierre Berthier for the type locality of Franklin Furnace (now Franklin Borough), New Jersey. Silliman (1920) translated Berthier's article: "As the chemical nomenclature cannot in every instance furnish a name, I propose to give it that of The Franklinite, in order to remind us that it was found, for the first time, in a place to which the Americans have given the name of a ...
Franklinite was a very important ore of zinc, together with the other zinc minerals at the Franklin and Sterling Hill mines. Now, however, those mines are no longer active, so Franklinite is no longer used as an ore of zinc. Large crystals of Franklinite are popular among collectors.

Franklinite definition is - an iron-black slightly magnetic mineral ZnFe2O4 consisting of an oxide of iron and zinc occurring in octahedral crystals or massive and constituting a member of the magnetite series.
Franklinite is one of the minerals found at Franklin, New Jersey, a world famous locality that has produced many formerly unknown and exotic mineral species. It is found in large enough quantity to serve as a ore of zinc and manganese, two important strategic and industrial metals.
Other articles where Franklinite is discussed: magnetite: franklinite (zinc iron oxide, ZnFe2O4), jacobsite (manganese iron oxide, MnFe2O4), and trevorite (nickel iron oxide, NiFe2O4). All are magnetic, although franklinite and jacobsite are only weakly so; magnetite, which frequently has distinct north and south poles, has been known for this property since about 500…
