Feb 20, 2006 #1. From the early 1900's and until the 1940's, the Terlingua Mining District was the third largest mercury producing area in the United States. The mercury was produced from an ore called cinnabar. Cinnabar was first discovered in the Terlingua area in the 1880's. However, it took until the early 1900's for the mining of the ...

The Inca knew there was something sinister about the cinnabar they hauled out of the ground at Huancavelica in Peru hundreds of years ago. They called the mine the Mine of Death.

Extracting mercury from cinnabar is rather simple: the rock shale is crushed, heated in a kiln, and the resulting mercury vapor is condensed and drained into a metal-lined "flask.". You can find tailings and talus from the extraction process that have been deposited in mounds throughout the area.

Cinnabar (HgS) is an important mineral with two important uses in the ancient world: 1) it can be selectively ground and used as a versatile red pigment for use on murals, ceramics, and gold masks (Petersen, 1970/2010; Brooks et al., 2008) or, 2) it can be retorted to produce mercury (Cabrera la Rosa, 1954; Craddock, 1995; Brooks, 2012).
