Mercury from mineral deposits and potential environmental impact

  title={Mercury from mineral deposits and potential environmental impact},
  author={J. Rytuba},
  journal={Environmental Geology},
Abstract.Mercury deposits are globally distributed in 26 mercury mineral belts. Three types of mercury deposits occur in these belts: silica–carbonate, hot-spring, and Almaden. Mercury is also produced as a by-product from several types of gold–silver and massive sulfide deposits, which account for 5% of the world's production. Other types of mineral deposits can be enriched in mercury and mercury phases present are dependent on deposit type. During processing of mercury ores, secondary mercury… Expand
Isotope geochemistry of mercury in source rocks, mineral deposits and spring deposits of the California Coast Ranges, USA
Abstract We present here the first study of the isotopic composition of mercury in rocks, ore deposits, and active spring deposits from the California Coast Ranges, a part of Earth's crust withExpand
Review of characteristics of mercury speciation and mobility from areas of mercury mining in semi-arid environments
The speciation of mercury—including most phase minerals, secondary phases, gaseous and aqueous species—is very important for evaluating the environmental impact and mobilization of this contaminant.Expand
Mercury isotope constraints on the source for sediment-hosted lead-zinc deposits in the Changdu area, southwestern China
The Lanuoma and Cuona sediment-hosted Pb-Zn deposits hosted by Upper Triassic limestone and sandstone, respectively, are located in the Changdu area, SW China. Mercury concentrations and Hg isotopicExpand
Fluid properties and sources of Sixiangchang carbonate-associated mercury deposit, southwest China
Mercury mines in Guizhou province are the main base of mercury production and the most important resource base in China. The San-Dan mercury belt in Guizhou province contains a series of importantExpand
Contribution of contaminated sites to the global mercury budget.
The information presented here is needed by governments and NGO's in order to re-focus resources in making decisions regarding mitigation and remediation strategies on a global level. Expand
Comparison of mercury distribution and mobility in soils affected by anthropogenic pollution around chloralkali plants and ancient mining sites
Abstract A comparative study of total mercury, elemental mercury and mercury fractionation has been performed on particle-size fractions of soils affected by anthropogenic sources of differentExpand
Metallogeny and environmental impact of Hg in Zn deposits in China
Abstract Zinc smelting is currently regarded as one of the most important atmospheric Hg emission sources in the world. In order to assess the potential environmental impacts of Hg from Zn smeltingExpand
Mining, metallurgy and the historical origin of mercury pollution in lakes and watercourses in Central Sweden.
Data on long-term mercury pollution in 16 sediment records from 15 lakes indicates that direct release of mercury to lakes and watercourses was already significant prior to industrialization (<AD 1800), which suggests that the present-day problem of elevated mercury concentrations in the Bergslagen region can trace its roots back to historical mining.

Assessing mercury distribution using isotopic fractionation of mercury processes and sources adjacent and downstream of a legacy mine district in Tuscany, Italy
Abstract Mercury (Hg) concentrations and isotopic compositions in a range of sample types collected from the legacy Abbadia San Salvatore Mine (ASSM) area were used to evaluate the distribution of HgExpand
Mercury and in situ sulfur isotopes as constraints on the metal and sulfur sources for the world’s largest Sb deposit at Xikuangshan, southern China
It has been well established that metal and sulfur sources in mineral deposits can be very difficult to identify, especially for ore deposits hosted in sedimentary rocks. Using the world’s largest SbExpand

Mine drainage from mercury mines in the California Coast Range mercury mineral belt is an environmental concern because of its acidity and high sulfate, mercury, and methylmercury concentrations. TwoExpand
Mercury in Zinc Deposits: Economic Geology of a Polluting Element
Zinc concentrates with a mercury content of >600 tons are processed by zinc smelters each year, with primary zinc producers contributing significantly to anthropogenic mercury emissions. The chiefExpand
Atmospheric mercury emissions from mine wastes and surrounding geologically enriched terrains
Abstract.Waste rock and ore associated with Hg, precious and base metal mining, and their surrounding host rocks are typically enriched in mercury relative to natural background concentrations (<0.1Expand
Mercury vapor and other volatile components in the air as guides to ore deposits
Abstract Several gaseous elements and compounds have been found to occur in anomalous concentrations in soil gas or air over mineral deposits. These gases or vapors include mercury, sulfur dioxide,Expand
Annual emissions of mercury to the atmosphere from natural sources in Nevada and California
Abstract.The impact of natural source emissions on atmospheric mercury concentrations and the biogeochemical cycle of mercury is not known. To begin to assess this impact, mercury emissions to theExpand
Characterization and speciation of mercury-bearing mine wastes using X-ray absorption spectroscopy.
Use of this technique, in conjunction with standard microanalytical techniques such as X-ray diffraction and electron probe microanalysis, is beneficial in the prioritization and remediation of mercury-contaminated mine sites. Expand
Distribution, speciation, and transport of mercury in stream-sediment, stream-water, and fish collected near abandoned mercury mines in southwestern Alaska, USA.
These stream-water results indicate that most of the Hg transported downstream from the mines is as finely-suspended material rather than dissolved Hg, which is below the 1000 ng/g action level for edible fish established by the US Food and Drug Administration (FDA). Expand
Global Mercury Pollution and its Expected Decrease after a Mercury Trade Ban
The high toxicity of methyl mercury (MeHg) is well known, as is the existence of transformations between metallic Hg and MeHg. As a consequence the industrialised countries have adopted Hg-freeExpand
Gold in the volcanogenic mercury-rich sulfide deposit Långsele, Skellefte ore district, northern Sweden
The mineralogy of gold from a volcanogenic sulfide deposit in northern Sweden (Långsele) was studied. The enrichment of gold and silver in massive ore occurs associated with an intrusive metadoleriteExpand
