Frohbergite (, title by proper name: Max Hans Frohberg), also iron telluride is a rare hydrothermal mineral from the sulfide class, in composition — iron telluride with the ideal formula FeTe2 (contains 82.05% tellurium and 17.95% iron).
Frohbergite occurs in tellurium-rich veins of hydrothermal deposits, sometimes as a thin rim on the periphery of chalcopyrite or as inclusions in native gold, petzite or chalcopyrite. It belongs to the marcasite group and forms a mineral line with mattagamite. Frohbergite most often occurs as fine-grained aggregates.
