It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments. Cinnabar generally occurs as a vein-filling mineral associated with volcanic activity and alkaline hot springs.
red cinnabar (α-HgS, trigonal, hP6, P3221) is the form in which mercury is most commonly found in nature. Cinnabar has rhombohedral crystal system. Crystals of red are optically active. This is caused by the Hg-S helices in the structure. [5] black metacinnabar (β-HgS) is less common in nature and adopts the zinc blende crystal structure (T 2 ...
Idrija is one of the few places in the world where mercury occurs in both its elemental liquid state and as cinnabar (mercury sulfide) ore. The subterranean shaft mine entrance known as Anthony's Shaft ( Antonijev rov ) is used today for tours of the upper levels, complete with life-sized depictions of workers over the ages.
The Mariscal Mine, also known as the Lindsey Mine and the Ellis Mine, was a source of cinnabar ore that was refined at the Texas site into mercury. The mine is located in what is now Big Bend National Park. The mine produced a total of 1400 flasks of mercury, each weighing 76 pounds (34 kg), accounting for almost a quarter of the mercury ...
The Guadalupe mine produced about 10% as much mercury as the New Almaden. There are several smaller mines in the mining district, but their ore production was not significant. The only significant quicksilver ore is cinnabar; other sulfides are present in small quantities. Mining, other than a single placer deposit of cinnabar, was underground.
The cinnabar ore, known also as mercury sulfide (84 parts mercury to 16 parts sulfur), was treated in furnaces and retorts near the mine. The essential refining method was to turn the mercury into gas and recondense it to quicksilver.

It is found either as a native metal (rare) or in cinnabar, metacinnabar, sphalerite, corderoite, livingstonite and other minerals, with cinnabar (HgS) being the most common ore. [46] [47] Mercury ores often occur in hot springs or other volcanic regions. [48] Beginning in 1558, with the invention of the patio process to extract silver from ore ...
