  3. Microstructural characteristics of gold-rich gold-iron alloys

    Chou, Chen-ChiaUniversity of Illinois at Urbana-Champaign2011

    As a typical spin-glass alloy system with diverse controversies on its magnetic properties and atomic arrangements, Au-rich Au-Fe alloys with Fe content from 10.7 to 33at% were studied to clarify their microstructural characteristics. As a consequence and in comparison with previous work, some …

  6. The gold absorption properties of shaly material from Beatrix Gold Mine

    University of Pretoria1994

    Shaly material from Beatrix Gold Mine has been found to be capable of adsorbing gold from cyanide solutions. Black shale bands occur in the reef zone at Beatrix Mine, but because of the mode of occurrence of the shale bands selective mining cannot be practised and ore delivered to the plant is …

    Samaimongkol, PanuponVirginia Tech2018

    … compound AuAl₂, also known as purple gold, originates from surface plasmons (SPs). This contrasts to a previous assumption that this color is due to an interband absorption transition. The existence of SPs was demonstrated by launching them in thin AuAl2 films in the Kretschmann …

  13. Gold-enriched rims on placer gold grains: an evaluation of formational processes

    Groen, John CorwynVirginia Tech1987

    Placer gold is frequently reported to assay at overall higher values of fineness than the gold in the rock from which it was liberated. A related phenomenon is the historical discovery of many extremely large gold nuggets (up to 28 lbs) in the southeastern United States that have no apparent source …
