G'Day Fred, Thank you I'm glad you enjoy watching my video's many more to come👍 If you have sulfides yes roast them before chemical extract. Cheers Kev
obrigado senhor por compartilha sua experiência, eu lhe acompanho do Brasil , n entendo seu idioma , o computador tem a vantagem de ter o tradutor em escrita, por isso gostaria de saber se esta maquina q o senhor usa na trituração das pedra são usadas os disco de corte ? como o o senhor mostrou com lixadeira ?
Yeah, recovery from sulfides is a different ballgame. Several methods can have good success depending on cost/danger level you want to play with. Good stuff brother.
@@BiggestKev1960 I suggest a smelt...if you get 20% back off the smelt I'd switch to acid recovery. Cyanide would be cheaper/more effecient but, I don't like playing with cyanide...weigh out 100grams and send off for assay. Expensive but accurate. You could have some really rich sulfides on a microscopic level...you'll never see it...gold recovery is fun. :)
Hi buddy, I'm not sure, roasting the Sulfides only burns off the Sulphur to release the Gold, then the material can be panned. Thank you for your comment👍
