Cinnabar mercury ore from Nevada, United States. Cinnabar generally occurs as a vein-filling mineral associated with volcanic activity and alkaline hot springs. Cinnabar is deposited by epithermal ascending aqueous solutions (those near the surface and not too hot) far removed from their igneous source. [17]
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 ...
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 ...
Becker sought out the mine to test the theory of Robert Oxland, a physician and mineralogist, formerly on the staff of the Toland Medical College in San Francisco, California [77] who also held a patent for refining tungsten from tin ore. Oxland believed the cinnabar ore at Sulphur Bank had been formed from hot springs.
The principal source of cinnabar for the ancient Romans was the Almaden mine in northwest Spain, which was worked by prisoners. Since the ore of mercury was highly toxic, a term in the mines was a near-guaranteed death sentence. Pliny the Elder described the mines this way: Nothing is more carefully guarded.
The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). 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.

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. There is a high probability of undiscovered high-grade ore which could be found and exploited using modern techniques. [6]
