Some Quicksilver Prospects in Adjacent Parts of Nevada, California, and Oregon

Description: Abstract: This report summarizes the results of reconnaissance study of quicksilver deposits in the northwestern corner of Nevada, the northeastern corner of California, and Lake County, Oreg. made in August 1940. The Lene Pine district, Nevada, the Silvertown and Red Hawk properties in California, and the Currier and Glass Butte properties in Oregon were included. The first two of these require further development before a definite opinion as to their value can be formed. The Red Hawk mine has yielded high-grade ore, but the ore bodies so far worked are very small and scattered. The small amount of development at the recently opened Currier mine has yielded encouraging results. The deposits in the Glass Buttes are large but of such low grade that thorough sampling would be needed to determine their value. In general the region appears to warrant more attention from quicksilver prospectors than it has yet received.

Development of Equipment for the Purification of Mercury by Distillation

Description: Abstract: "An investigation of the mercury salvage program has resulted in the development of an improved high compacity type of distillation apparatus. The still, electrically heated and essentially automatic in its operation, will produce at a rate greater than 75 pounds per hour and develop a product 99.99% pure or better. This still will handle the lowest grade crude of amalgam that can pass through the feed lines and will continue to develop a pure prodcut for comparatively long periods of time. The clean-out operation is amazingly simple and convenient and may be done within one-half hour while the apparatus itself is still hot. Two models of this design are scheduled for installation in a mercury recovery room of the Alpha Analytical Department of Building No. 9207."

Leaching of Phase II Mercury Control Technology By-Products

Description: The U.S. EPA has issued a final regulation for control of mercury from coal-fired power plants. An NETL research, development and demonstration program under DOE/Fossil Energy Innovations for Existing Plants is directed toward the improvement of the performance and economics of mercury control from coal-fired plants. The current Phase II of the RD&D program emphasizes the evaluation of performance and cost of control technologies through slip-stream and full scale field testing while continuing the development of novel concepts. One of the concerns of the NETL program is the fate of the captured flue gas mercury which is transferred to the condensed phase by-product stream. These adulterated by-products, both ashes and FGD material, represent the greatest challenge to the DOE goal of increased utilization of by-products. The degree of stability of capture by-products and their potential for release of mercury can have a large economic impact on material sales or the approach to disposal. One of the considerations for mercury control technology is the potential trade-off between effective but temporary mercury capture and less effective but more permanent sequestration. As part of a greater characterization effort of Phase II facility baseline and control technology sample pairs, NETL in-house laboratories have performed aqueous leaching procedures on a select subset of the available sample pairs. This report describes batch leaching results for mercury, arsenic, and selenium.

Characterization of mercury forms in contaminated floodplain soils

Description: The chemical form or speciation of Hg in the floodplain soils of the East Fork Poplar Creek in Oak Ridge TN, a site contaminated from past industrial activity, was investigated. Hg speciation in the soils is an important factor in controlling the fate and effect of mercury at the site and in assessing human health and ecological risk. Application of 3 different sequential extraction speciation schemes indicated the Hg at the site was predominantly relatively insoluble mercuric sulfide or metallic Hg, though the relative proportions of each did not agree well between procedures. Application of x-ray and electron beam studies to site soils confirmed the presence of metacinnabar, a form of mercuric sulfide, the first known evidence of authigenic mercuric sulfide formation in soils.

The Mercury Photosensitized Reactions of Some Hydocarbons

Description: The problem was to study several hydrocarbons when they were subjected to ultraviolet light of 2536 Å in the presence of mercury vapor. It would be expected from the work of Stallings that the rupture of any tertiary hydrogen bond in the molecule would be the predominant effect. However, secondary and primary bond splitting would occur as well as some C-C bond rupturing, but these could be expected to a lesser degree than the first, since the t-hydrogen has the greatest reactivity.

FY09 assessment of mercury reduction at SNL/NM.

Description: This assessment takes the result of the FY08 performance target baseline of mercury at Sandia National Laboratories/New Mexico, and records the steps taken in FY09 to collect additional data, encourage the voluntary reduction of mercury, and measure success. Elemental (metallic) mercury and all of its compounds are toxic, and exposure to excessive levels can permanently damage or fatally injure the brain and kidneys. Elemental mercury can also be absorbed through the skin and cause allergic reactions. Ingestion of inorganic mercury compounds can cause severe renal and gastrointestinal damage. Organic compounds of mercury such as methyl mercury, created when elemental mercury enters the environment, are considered the most toxic forms of the element. Exposures to very small amounts of these compounds can result in devastating neurological damage and death.1 SNL/NM is required to report annually on the site wide inventory of mercury for the Environmental Protection Agency's (EPA) Toxics Release Inventory (TRI) Program, as the site's inventory is excess of the ten pound reportable threshold quantity. In the fiscal year 2008 (FY08) Pollution Prevention Program Plan, Section 5.3 Reduction of Environmental Releases, a performance target stated was to establish a baseline of mercury, its principle uses, and annual quantity or inventory. This was accomplished on July 29, 2008 by recording the current status of mercury in the Chemical Information System (CIS).

Measurements of Mercury Released from Amalgams and Sulfide Compounds

Description: This report covers work performed during FY 1998 in support of treatment demonstrations conducted for the Mercury Working Group. In order to comply with the requirements of the Resource Conservation and Recovery Act, as implemented by the US Environmental Protection Agency (EPA), the US Department of Energy (DOE) must apply amalgamation, the treatment standard for radioactively contaminated mercury, before disposing of these wastes. The Mercury Working Group under the Mixed Waste Focus Area sponsored a demonstration in which two commercial vendors demonstrated their technologies for the treatment of radioactive mercury from various DOE sites. The project, described in this report, addresses the need for data on the vapor pressure and degradation occurring in amalgamated mercury mixed low-level wastes generated during these demonstrations under a variety of conditions.

Development of a technique for mercury speciation and quantification using gas chromatography/mass spectrometry

Description: One element of concern to DOE is mercury. Mercury was used extensively at the DOE facilities in Oak Ridge, Tennessee from 1950 to 1963 in the process of making lithium deuteride, a component of nuclear weapons. Although both the inorganic and organometallic forms of mercury are toxic to humans, the organic compounds are often more toxic. Since the toxicity of mercury is a function of its chemical form, an understanding of the interactions between commercially discharged mercury, naturally occurring mercury, and the environment in which they are present is vital. In this report, the authors have been investigating gas chromatography/mass spectrometry (GC/MS) for the analysis of both the organometallic and inorganic forms of mercury in the same environmental sample (e.g., solutions, soils, and sludges). Although gas chromatography is the classical technique for analyzing organic molecules, (e.g., organometallic compounds) little has been done on the analysis of inorganic compounds. In a previous publication, the authors described how a solid phase microextraction (SPME) fiber could be used to sample organomercurials from aqueous samples. An alkylation reaction was then carried out to transform chemically mercury nitrate into dimethylmercury; subsequent GC/MS analysis of this compound permitted quantification of the inorganic constituent. Subsequently, several different alkylation reagents have been synthesized that methylate any inorganic mercury compound to methylmercury iodide. Here, the authors report results on alkylation reaction time and the effect of pH on the population of the product.

Mercury extraction by the TRUEX process solvent: I. Kinetics, extractable species, dependence on nitric acid concentration and stoichiometry

Description: Mercury extraction from acidic aqueous solutions by the TRUEX process solvent (0.2 M CMPO, 1.4 M TBP in n-dodecane) has not extensively been examined. Research at the Idaho Chemical Processing Plant is currently in progress to evaluate the TRUEX process for actinide removal from several acidic waste streams, including liquid sodium-bearing waste (SBW), which contains significant quantities of mercury. Preliminary experiments were performed involving the extraction of Hg{sup 203}, added as HgCl{sub 2}, from 0.01 to 10 M HNO{sub 3} solutions. Mercury distribution coefficients (D{sub Hg}) range between 3 and 60 from 0.01 M to 2 M HNO{sub 3}. At higher nitric acid concentrations, i.e. 5 M HNO{sub 3} or greater, D{sub Hg} significantly decreases to values less than 1. These results indicate mercury is extracted from acidic solutions {<=}{approximately}2 M HNO{sub 3} and stripped with nitric acid solutions {>=}{approximately}5 M HNO{sub 3}. Experimental results indicate the extractable species is HgCl{sub 2} from nitrate media, i.e., chloride must be present in the nitrate feed to extract mercury. Extractions from Hg(NO{sub 3}){sub 2} solutions indicated substantially reduced distribution ratios, typically D{sub Hg}< 1, for the range of nitric acid concentrations examined (0.01 to 8 M HNO{sub 3}). Extraction of mercury, as HgCl{sub 2}, by the individual components of the TRUEX solvent was also examined from 2 M HNO{sub 3}. The diluent, n-dodecane, does not measurably extract mercury. With a 1.4 M TBP/n-dodecane solvent, D{sub Hg} {approximately}3.4 compared with D{sub Hg} {approximately}7 for the TRUEX solvent. Classical slope analysis techniques were utilized to evaluate the stoichiometric coefficients of Hg extraction independently for both CMPO and TBP.

Decay of superdeformed bands

Description: One of the major challenges in the study of superdeformation is to directly connect the large number of superdeformed bands now known to the yrast states. In this way, excitation energies, spins and parities can be assigned to the levels in the second well which is essential to establish the collective and single-particle components of these bands. This paper will review some of the progress which has been made to understand the decay of superdeformed bands using the new arrays including the measurement of the total decay spectrum and the establishment of direct one-step decays from the superdeformed band to the yrast line in {sup 194}Hg. 42 refs., 5 figs.

Discrete-line transitions from superdeformed to yrast states in {sup 194}Hg and {sup 192}Hg

Description: Discrete-line {gamma}-ray decay from superdeformed (SD) to yrast states in {sup 194,192}Hg has been studied with the Gammasphere spectrometer. The previously established decay for the yrast SD band of {sup 194}Hg has been characterized further. In addition, one-step decays have been observed for {sup 194}Hg SD band 3, which fixes the excitation energy and spin of the last observed level of this band at E* = 7.455 MeV, J = 11{Dirac_h}. So far no direct decays from superdeformed to yrast states have been observed in {sup 192}Hg or in {sup 194}Hg band 2, a result which is consistent with fluctuations of the transition strengths.
