TitleFranckeite
DescriptionFranckeite, (Pb,Sn)6FeSn2Sb2S14 (lead tin iron antimony sulfide), is a rare sulfide mineral. It is found in the sulfide ores in Bolivia and Peru usually with other rare sulfides such as cylindrite, stannite, incaite and potosiite. Franckeite is a sulfosalt. Normally semi-metal ions such as antimony will substitute for the sulfur atoms, but in the sulfosalts they substitute for the metal ions and bond with the sulfurs.
LocationBolivia. Near Oruro.
