Hg and Au Recovery from Tailings
Recovering Hg and Au, with a Shaker Table from Tailings, Sudan, Africa
One of the really nice things about IRC, is the number of interesting channels and discussions, with numerous knowledgeable people. There was a link and discussion in ##chemistry on Freenode the other day, which showed the extraction of Mercury (Hg) and Gold (Au) from mining waste material, Tailings.
Interesting process and idea, especially, if this can be demonstrated to be commercially viable.
Granted anyone watching this video, who has a knowledge of Health and Safety issues around Hg, may want to look away.
Interesting reaction between Mercury (Hg) andNitric Acid ($HNO_3$).
