Definition of STIBNITE
: a mineral that consists of the trisulfide of antimony and occurs in orthorhombic lead-gray crystals of metallic luster or in massive form
Origin of STIBNITE
alteration of obsolete English stibine stibnite, from French, from Latin stibium antimony, from Greek stibi, from Egyptian sṭm
First Known Use: circa 1854
Antimony sulfide (SbS), the principal ore of antimony. This sulfide mineral has a brilliant metallic lustre, is lead or steel gray in colour, and fuses (melts) readily. Stibnite occurs in low-temperature hydrothermal veins (seehydrothermal ore deposits) and in replacement deposits. Significant deposits have been found in China, Japan, and the U.S. (Idaho, California, and Nevada). Stibnite is used in making matches, fireworks, and percussion caps and was used by the ancients as a cosmetic (called kohl) to increase the apparent size of the eye.
