The Gold and Platinum recovery process

2007-10-12 08:18:27 · 5 answers · asked by hoody 1 in Science & Mathematics Engineering

in this process,what would be the metal on the Cathode and, what would be the metal on the Anode? what would be the solution consist of?What we must add on the solution as a catalyst? Should we use Potasium Cynide in the solution?

Carbon anodes would work.
For the cathode, either gold or platinum would
improve the purity of your extract.
(Why add another metal?).

KCN ??????
If you have to ask this question, stay the heck away
from cyanides. They can produce a highly poisonous gas
at the anode, and KCN is toxic enough to be absorbed
through the skin. The dust is also dangerous.
I assume this is a small project. Aqua regia is far safer
for amateurs to handle. It will just burn you, and the toxic
gases are not as sneaky. (They will be quite unpleasant to
be around at less-than-lethal levels.)

Precise Voltage Control is important to the process,
(Wiki 'Half cell potentials` for the ions in question.)

Gold Electrolysis

The material that you want to separate the gold from is the cathode, a piece of the pure metal, would be the anode. A 1/10 ounce, or less piece of gold would do very well since it can be beaten very thin, to be the anode. A Gold Chloride, or other gold based electrolyte would be the medium of transfer. That medium just has to be conductive, therefore some what acidic.

BY PASSING AN ELECTRICAL CURRENT THROUGH A GOLD BEARING SOLUTION THE GOLD IS DEPOSITED ON THE POSITIVE ELECTRODE. IT IS CALLED GOLD PLATING. IT WORKS WITH SOME OTHER METALS.

I am very sorry but the collector/plate is the cathode (negative charge) not the anode (positive charge). the positive charge is referred to as the sacrificial anode and plates to the cathode (negatively charged collector).
