Dear masters;
i dont have experience but i watched and read 100s of hours about gold refining (Well, as you can guess the boredom during these quarantine days). And i decided to try at least one experience. My friend has a toner refill shop. i took around 230 used ink cartridges and peeled them off all ready to process.
I'm gonna do that not for benefit, just for a one time hobby/experience. That's why i don't care how much the chemicals cost. All i want is a fast, without fire/heat machine, max amound of gold, less risky for health (I'll have all the precautions but anyway), and minimum %90 of pure gold in the final dust.
But eeeevery one has a different opinion and also not many information about "ink cartridges gold refining". Today i made a test with a few of ribbons. Because i wasn't sure if the chemicals can reach to the metals inside through the both side plastic cover (don't know the name of the material, sorry). So i put two ribbons into a glass and add sulfuric acid as someone said it can dissolve the plastic. it didn't. then i tried with another two ribbons as this time adding directly AR. (Hcl %33 and nitric asid %56) (5/1). And after a couple of hours, i saw that liquid turned into greenish yellow and all the squared gold dots are gone/dissolved.
i think it's good so far. (if not, please inform me). But i know that there is also a big amound of copper dissolved. So what can i do after that? Just filter and add smb? (some puts urea some not). Any middle process? Or some other idea about from the beginning till the end? As i mentioned, as long as the process & result are as i want, no problem about the access to any chemicals.
Thanks for your answers in advance.
