Production was resumed ahead of schedule as the drainage work was completed. The mine recovery plan was updated, and it is expected that Oktyabrsky (annual ore output- 5 million mt) will fully resume production by the end of April

  • Simultaneous quantitative analysis of arsenic, bismuth

    The method detection limits for arsenic, bismuth, tellurium, and selenium are 0.19 μg/g, 0.10 μg/g, 0.11 μg/g, and 0.08 μg/g, respectively. This method was successfully applied to the simultaneous determination of arsenic, bismuth, tellurium, and selenium in soil samples.

  • Evaluation of the Content of Antimony, Arsenic, Bismuth

    Baby foods, from the Spanish market and prepared from meat, fish, vegetables, cereals, legumes, and fruits, were analyzed to obtain the concentration of antimony (Sb), arsenic (As), bismuth (Bi), and tellurium (Te) as toxic elements and selenium (Se) as essential element. An analytical procedure was employed based on atomic fluorescence spectroscopy which allowed to obtain accurate data at low

  • Bismuth Tellurium Selenide AMERICAN ELEMENTS

    Bismuth Tellurium Selenide (Bismuth Selenide Telluride, or Selenium-doped Bismuth Telluride) is a novel semiconductor material. High purity, submicron and nanopowder forms may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical

  • Coordination chemistry of homoatomic ligands of bismuth

    15/02/2015· In their coordination chemistry, the heavy main-group elements bismuth, selenium and tellurium make use of their paired or unpaired p-electrons to establish covalent bonds to the transition metals. As a rule bismuth acts as a one-electron donor, whereas the chalcogens are two-electron donors. The transition metal cation typically reaches the electron count of 18. In the case of some of

  • Paper chromatographic analysis of selenium, tellurium

    The bismuth and tellurium content applied to the paper strips in the figures was approximately 0.3 mg for each element with tracer polonium and negligible amounts of selenium. RESULTS No solvent mixture was found that would separate polonium and tellurium in hydrochloric acid medium. Some of the better results were with the solvent mixtures demonstrated in Figs. 1 and 2. Lower hydrochloric

  • Simultaneous Quantitative Analysis of Arsenic, Bismuth

    bismuth, tellurium, and selenium include atomic absorption spectroscopy (AAS), 7 hydride generation atomic ßuorescence spectrometry (HG-AFS), 8 and inductively coupled plasma Ð mass spectrometry (ICP-MS). 9 Because hydride-generation atomic ßuorescence spectrometry has a high sensitivity, it has been used widely in geological exploration. 10,11 In 1969, Holak Þrst proposed the technique of

  • Selenium and Tellurium Statistics and Information

    In the late 1990's, the use of selenium (usually with bismuth) as an additive to plumbing brasses to meet no-lead environmental standards became important. The average price for selenium in 2000 was $3.82 per pound. Tellurium is a relatively rare element, in the same chemical family as oxygen, sulfur, selenium, and polonium: oxygen and sulfur are nonmetals, polonium is a metal, and selenium

  • On the different adsorption behavior of bismuth, sulfur

    The deposition behavior of sulfur, selenium, tellurium and bismuth on the Pt(775) surface has been studied by cyclic voltammetry. It has been found that bismuth and tellurium deposit preferentially on the step sites. Once the step sites are fully covered by these adatoms, the deposition on the terrace starts. Conversely, step decoration cannot be achieved with sulfur and selenium.
