    Osa The Infrared Properties Of Gold Smoke Deposits

    An interpretation of the infrared optical properties of gold smoke deposits is presented together with new experimental results. This interpretation is based on an application of classical electromagnetic theory. The gold smoke deposits are assumed to interact with infrared radiation as if they were sheets of an essentially uniform material which is characterized by an average electrical ...

    Gold In Virginia

    Gold was mined in this area from 1832 through 1938. On this site, two heavy metals arsenic and mercury and the chemical cyanide were used in the processing of gold. Arsenic was leached into the ground to distinguish the gold ore from iron pyrite. Once the gold ore was found it was amalgamated into pure gold using mercury and cyanide.
