Gold Assay by Electrodeposition (1 reply)

Gold determination by electrodeposition (Electrophoretic deposition) using graphite carbon elecrode or glassy carbon electrode. Do you have any professional paper?
We used to analyse Gold by fire assay finished by AAS or gravimetric but as you know the cost in such technics is very high and the selection of flux may leads to errors specially in low grad (0.2 ppm) analysis in my project i'm working on something differents doing it by electrochemistry precisely the technic I mentioned I my first discussion.
Is there someone doing it already, anything that can help and suggestions...this what the discussion is about.

You could have procedure written to analyze the low grade ore you describe. However is is necessary to know your major, minor, and tertiary elements that you are the working with.
I personally do not use fire assay. If you have a AA it is fairly easy, you have to watch your temperature to get your solution in solution with no niter used but only HCL and H2O2; no electrolysis as this requires a large amount of current.
