I prosesed 5 lbs of cell phone boards with out removing the small componants and came out with a big mess, i did get a small amount of gold but in my opinion it was not worth it. I got another 5or6 lbs of cell boards and dont want to mess with them, if anyone does iwould sell or trade them.
texan said:I have spent most of the last year learning the procedures that others have blazed the trail on in this forum. I have been gradually adopting these procedures for doing cell phones and I am not finished yet developing a set of protocalls that work for me and the small lab I have set up in my garage. I have over 10k of complete cell phones of every make and model you can imagine. The amount of material you have is just enough to get you started in this hobby...and that is what it will have to be because there is not enough money/time to realize out of it any kind of living...but it sure is fun to watch all the gold swim around in the flask after separating it from whatever part it came from. I have also come to believe that a large percentage of the gold in the phones is hidden in the microprocessors and other integrated circuit chips. I have pulled apart several chips that show no gold on the surface and the dang things look like Fort Knox under the microscope. You can see some of the photos I have posted by pulling my other posts on the forum. It seems like the more the designers try to miniturize electronic components, the more they find they need the gold for heat disapation, electrical conductivity etc.
Without going into a procedural manual specific to cell phones at present... study the forum to get started. Separate the phones into component parts and process with the procedures outlined here by others....thats how I started.
One more note...I know there are other PM's in the phones but I am just concentrating on the gold at present and nothing is be being thrown away...
Be safe.

The use of nitric is an entirely different process and can be very dangerous until you have the skills necessary to handle it. I have a background working in a chemistry lab and have found no need to get any nitric so far.
Take your time...
Have you read C.M. Hoke's book yet on gold refining? It is required reading for this forum.
