Abstract. This chapter describes the main mercury ore Cinnabar (abbrv. cin), as seen with optical, reflected light microscopy. Compositional data, main properties and optical parameters are first summarized (introductory table and preliminary remarks). The microscopic description of the ore is then presented, following a systematic scheme.

In spite of a thorough research of the 19 th century scientists, vitriols of mercury were never observed in the ore deposit. A canary-yellow mercuric sulfate schuetteite, however, can be found on the bricks of the mercury ore smelters. In Idria, it was first described by SEYFRIEDSBERGER (1890). This supergene mineral crystallizes …

Cinnabar (α-HgS) is the most common sulfide of mercury while metacinnabar (β-HgS), a high-temperature homogeneous polymorph of the mercury sulfide, is relatively rare, and the α phase of cinnabar transforms to the β phase at 344 °C. Meanwhile, there is a complete isomorphic series between HgS and HgSe, and the …

The ore of mercury, cinnabar, is soft and dark red, and native mercury is one of a few metals that is liquid at room temperatures. Cinnabar from Almaden, Spain, the world's oldest producing mercury mine, was used during Roman times, and the chemical symbol for mercury (Hg) is from "hydrargyrum," from the Greek word meaning liquid silver.

Mercury is extracted from cinnabar ores (HgS) by heating the ores in a current of air and collecting the vapor formed. The reaction for this extraction can be shown as: HgS + O2 → Hg + SO2. China has been the top producer of elemental mercury in the world with almost two-thirds global share of mercury ores [5].
