    Urinary mercury among those who heat mercury to remove it from the gold or who amalgamate the gold with mercury can be extraordinarily elevated. Many of these studies. 10 17 . report urinary mercury concentrations well above 50 µg mercury/g creatinine, a urinary concentration where renal tubular effects are believed to occur, 18. and/or 100

  • Gold Smelting Refining Process

    Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silver gold concentrates can be smelted too. Under this consideration, a concentrate must contain at least 20 oz/t of gold. Obviously, if the higher grades are better and 50 oz/t is a good average value.

    Where there is gravity recoverable gold, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk.

  • Map Showing Gold Concentrations from Stream

    Gold concentration in the Humboldt River basin, ranges from below detection limits (0.002 and 0.0005 ppm) to 4.68 ppm. The weathering of Au bearing sulfides, sulfosalts, and tellurides can release aqueous and particulate gold into the stream environment (Edwards and others, 1995), which can be redistributed mechanically and geochemically.
