  • Pyromet gold recovery method Pyrometallurgy:

    Pyromet gold recovery method (1 reply) T Scotman 4 years ago Scotman 4 years ago I have a supply of high grade (+50gm/t) wood chip ash, as well as a supply of loaded carbon fines What would the process be to recover the gold from these products? Is there a pyromet process that one could undertake, and then leach the gold? David 4 years ago David 4 years ago Like Did you see httpsThe gold in the ash will all be metallic but it will be so finely divided that gravity separation will not work The gold can be dissolved in aqua regia or in cyanide solution Usually with either of these leaches you carry out filtration after the dissolution and any unashed carbon on the filter is sent for reashingGold recovery from carbon ash Pyrometallurgy:Use Add New Topic to ask a New Question/Discussion about Pyrometallurgy and I Currently have an aqua regia refining plant from italy which refines 15kg Gold at a timeafter our refining process we notice that the gold we refine is normally between 99969999however the final surface of the gold has rough edges and has a dulW Last replied to by Wieslaw Wodecki Au powder afterPyrometallurgy: Roasting, Smelting, Refining &
