Stibnite or antimonite is sulfide metalloid mineral of antimony with chemical formula (Sb2 S 3 ). The color is shiny lead-gray tarnishing to black with massive, granular, radiating, and elongated crystals habits ( Fig. 1.50 ). The mineral contains 71.7% antimony in its natural purest form. Stibnite crystallizes in orthorhombic system, needle ...
Summary: Mining at the Stibnite Gold Project would be accomplished using conventional open pit hard rock mining methods. Mining is planned to deliver 8.05 Mst of ore to the crusher per year (22,050 st/d), with stockpiling by ore type (low antimony sulfide, high antimony sulfide and oxide).
Principal contributors to the toxicity potentials are lead, arsenic, copper, and mercury. Although the heavy metal content in newer flat panel display devices creates less human health toxicity potential than that in CRTs, for ecological toxicity, the new devices are worse, especially because of the mercury in LCD TVs and the copper in plasma TVs.

The dark red silver ore is a sulphide of silver and antimony ; the light red contains arsenic in the place of antimony. The ores of silver occur in veins traversing granitic and gneissic rocks, clay slate, mica schist, limestone, and are usually associated with the ores of iron, copper, load (galena being always argentiferous), zinc.
