recovery silver from silver cyanide mud

Recover silver from Silver Potassium Cyanide Gold

17/08/2009· The collected silver/zinc mud must be rinsed very well with hot water, in a filter, in order to remove all traces of cyanide solution. The next step uses acid to remove the excess zinc and any cyanide left in the mud will produce hydrogen cyanide, which is the gas used in prison gas chambers. No matter how well you've rinsed, don't attempt this unless you have a good FUME HOOD.

Recovering Silver from Silver Chloride Gold Refining

11/04/2015· Silver chloride will dissolve in ammonium hydroxide, sodium or potassium cyanide, or sodium thiosulfate. Sodium thiosulfate (Na2S2O3 photo hypo) would definitely be the safest to use of the three. I've never tried to dissolve fused AgCl in Na2S2O3 and would imagine it would go slowly. After dissolving in Na2S2O3, you can use zinc dust to precipitate the silver. If you use an excess of zinc
