Jul 05, 2016 Stibnite is antimony sulfide, but it looks like silver. For that reason, the huge, shining metallic crystals were once fashioned into magnificent eating utensils. Cinnabar, mercury sulfide, is the most toxic mineral to handle on Earth. The name itself means dragons blood.

Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). Mined ore deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins.

Thermal Reduction of Mechanically Activated Cinnabar (HgS

The reduction of cinnabar (HgS) and stibnite (Sb2S3) by hydrogen was investigated. These investigations were performed in the temperature region 636–765 K for cinnabar and in the region 825–954 K for stibnite. It has appeared that the mechanical activation positively affects the thermal reduction of the sulphides. The thermal decomposition of HgS is accompanied by a change in

Stibnite

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

Common naturally occurring sulfur compounds include the sulfide minerals, such as pyrite (iron sulfide), cinnabar (mercury sulfide), galena (lead sulfide), sphalerite (zinc sulfide), and stibnite (antimony sulfide); and the sulfate minerals, such as gypsum (calcium sulfate), alunite (potassium aluminium sulfate), and barite (barium sulfate).

Geochemistry and exploration criteria for epithermal

Nov 01, 1991 Cinnabar- and stibnite-bearing epithermal vein deposits are found throughout the Kuskokwim River region of southwestern Alaska. A geochemical orientation survey was carried out around several of these epithermal lodes to obtain information for planning regional geochemical surveys and to develop procedures which maximize the anomaly: threshold contrast of the deposits.
