“…Production from Almadén represents more than 30% of the total known Hg produced worldwide (22,23). Mining activity at the Almadén mine ceased in May 2002, but significant piles of mine-waste calcine remain throughout the Almadén district.…”

In vitro bioaccessibility (IVBA) studies were carried out on samples of mercury (Hg) mine-waste calcine (roasted Hg ore) by leaching with simulated human body fluids. The objective was to estimate potential human exposure to Hg due to inhalation of airborne calcine particulates and hand-to-mouth ingestion of Hg-bearing calcines. Mine waste calcines collected from Hg mines at Almadén, Spain, and Terlingua, Texas, contain Hg sulfide, elemental Hg, and soluble Hg compounds, which constitute primary ore or compounds formed during Hg retorting. Elevated leachate Hg concentrations were found during calcine leaching using a simulated gastric fluid (as much as 6200 μg of Hg leached/g sample). Elevated Hg concentrations were also found in calcine leachates using a simulated lung fluid (as much as 9200 μg of Hg leached/g), serum-based fluid (as much as 1600 μg of Hg leached/g), and water of pH 5 (as much as 880 μg of Hg leached/g). The leaching capacity of Hg is controlled by calcine mineralogy; thus, calcines containing soluble Hg compounds contain higher leachate Hg concentrations. Results indicate that ingestion or inhalation of Hg mine-waste calcine may lead to increased Hg concentrations in the human body, especially through the ingestion pathway.

“…Many of the mercury deposits of the California Coast Ranges have small quantities of oil, solid bitumen, and hydrocarbon minerals that are genetically associated with the mercury ore (Bailey, 1959;Peabody, 1990Peabody, , 1993Peabody and Einaudi, 1992). The K2 samples are oils genetically associated with mercury deposits and have an isotopic composition similar to the other Cretaceous oils.…”

“…Samples of gas, oil, coal and oil shale themselves can also contain high mercury concentrations. The association is attributed to a common dependency of hydrocarbons and mercury upon high geochemical gradients, high fluid fluxes and structural focussing of fluids (Ozerova et al 1992;Peabody 1993). Work by Russian geologists in particular has suggested that in addition to a hydrocarbon exploration tool the association can be used to explore for mercury ore deposits.…”
