Does anybody know about the best way to recover gold from resin coming from resin filled cartridges that were used to recover gold from the first rinse after the gold bath in an ENIG (Emersion Nickel Immersion Gold) process used as finish in PCB manufacturing?
The goal is to use a furnace with the sample in a crucible and then heat up to 1300 Degr C. At about 500 to 600 Degr. C the resin starts to burn. While temperature is rising to reach the melting point of the gold i would like to take out the crucible and pour the melted gold into a mold. Are there any steps that should be added in between? Maybe addition of borax and/or baking soda at some point? Do i need to get rid of the carbon resulting from the incineration first?
Thank you in advance for your response!
