related to weathering of gold ores and gold-nugget formation [19–21], in volcanic fumaroles [22,23], in Carlin-type gold deposits [24,25], and also in active geothermal systems [2,26–28]. Finally, metallic sulfide nanoparticles are significant components in the "black smoke" discharging from submarine hydrothermal vents [29–31].
Thiosulfate leaching is being used for the Nevada preg-robbing gold ores. Other noncyanide lixiviants have been reported (Aylmore, 2005) that may be applicable to preg-robbing gold ores, including the alkaline sulfide system (Anderson et al., 2005), the electrochemistry of the thiourea system (Parker and Hope, 2008), and the halogens. 2.
