Gold recovery from GPC (Gold Potassium Cyanide) solution is a very profitable
business. I am going to give you a very easy process for gold recovery from
gold potassium cyanide solution. Gold can be easily recovered from this
solution with zinc dust. It is a metal displacement theory.
Heat the solution to around 60 degrees Celsius. You may
either use a PVC/Plastic or glass container for it. You can use a glass heater
for heating the solution. Add five to
ten grams of (325 mesh) zinc dust per liter. Stir the solution with a glass rod
for about five minutes at least five times with a gap of one hour (each time). Leave
the solution for a night. But make sure the solution should remain hot
throughout the night. Zinc dust will displace all the gold from the solution by
the morning. Pour out all the liquid into another container, leaving behind the
gold dust.
This gold dust has some zinc impurity in it. So, it needs to
be refined. For this, you treat it either with dilute sulfuric or nitric acid
for five to ten minutes on a lighter flame. This treatment will produce some smoke.
So, use a properly ventilated place for it. During the reaction, bubbles come
to the surface and break and give out smoke of green color. It is an indication
of the zinc dust being dissolved into the acid. When the gold dust is refined,
the bubbles and green smoke stop completely. Wash this refined gold dust with
water three to four times. Dry and melt it into a gold button.
Note: I have uploaded a video regarding it on my YouTube

The comments and mails that I receive from people suggest
that I am talking about producing GPC (Gold Potassium Cyanide) solution for
gold recovery. It is not that. GPC is used in gold plating different materials
such as artificial jewelry water taps, door handles and many more things. Some companies
don’t recover gold from the spent up cyanide solutions. They prefer to sell it
to the outsiders. So, this video is for those who want to make money through
GPC by purchasing it from the gold plating plants. You can really make a lot of
money by recovering gold from this exhausted GPC solution. Please use safety
gear if you do this process.
