[@julianalcorso5703]

Hey Owl, Another great vid. Mate, I wonder if I can ask you to do an experiment. My new lab is not ready yet and I have been wanting to try the following. Strip completely 6 - 10 motherboards with an air chisel or hammer and chisel, and do a rough sort to remove aluminum capacitors and other obvious junk. Then either incinerate and crush or boil in hot H2SO4, remove any magnetic materials, then boil in HCL + Some citric to remove tin. Then dissolve all metals other than gold in hot HNO3. Recover Ag (and then any Pd) then recover Au with Aqua Regia. My theory is that sorting components (if not making a video) is a waste of time and that nearly everything can be recovered by simply incinerating, grinding and recovering. As you are one of the few refiners on KZbin who understands the chemistry so I thought you might be up for the challenge,🙂

Looks like the sodium hydroxide is a bit cleaner process than ashing these type of capacitors. Thanks for showing! I have a nice stockpile of these older caps. Id like to use the lye to strip a few other ones that look like they may be pd/ag type mlcc inside.

[@OwlTech333]

NaOH works on the clay coated MLCCs, for the plastic ones you'll need H2SO4

[@razor1983]

I am trying right now the NaOH method on some blue ones and I think they are plastic. I have been soaking them for 2 hours and nothing is happening. I will try to wash them and then add H2so4 and see if thar works

[@razor1983]

One more thing if I'm not to nosy. How can you tell when the acid is saturated? Thank you once more for sharing with us!

[@OwlTech333]

I wanted to show another method

[@matthewmartinez1091]

From my understanding brother something that is highly caustic to boiling can desovle metals too. Boiling in HCL will remove base metals but tin should be clear now purple colloidal gold is purple and also from my understanding there's supposes to be small amounts of gold in MLCCs.

[@OwlTech333]

no gold in this mlccs, you can find gold on the surface mount mlccs wich is leached from the pcb by the solder

[@OwlTech333]

the puprle colour is from titanium salts formed from the dissolution of the ceramic substrate - barium titanate

[@matthewmartinez1091]

@@OwlTech333 but I have seen a video where they refine Metals with caustic soda so you probably did lose some metals their brother.

[@OwlTech333]

Not with this process and caustic is used only to remove the coating

[@vipsantorini6997]

May i ask how you remove the slag from the alloy using HCl since it had Ag in it?

[@OwlTech333]

the slag does not contain Ag, the alloy does. With the prolonged boiling HCl I removed the borax glass not the silver from the alloy

Heya ! Another method for recovery which will be of great interest for those who don't have furnace at home ! It takes a long time to get rid of base metals using HCL but... It's the costless method of all ! Anyway, i must ask you about your last video for bga caps and the problem of gold yeld. Did you recover more gold or did you bought bad materials ( Some bga caps do not contain any gold instead of their "gold corner indication".) Thanks for sharing your work and wish you a good summer time.

[@colonialcharlie8702]

I think mostly missing gold was caused by the amount of copper heat sink bgas. The yeild estimates are likely more accurate if they are sorted. The batch seemed to be mostly the heat sink ones. 1kg heat sink bgas will likely be similar yeild to less than 1/5th kg regular/gold corner bgas

[@OwlTech333]

I think I've been given predominantly copper wire chips but anyway I keep all my slags so there will be a big remelt someday

[@kamelsamer5768]

@@colonialcharlie8702 what do you mean by "missing gold"? Why are all gold recoveryists complaining about missing or lost gold? Could someone please explain how gold is lost?

[@colonialcharlie8702]

@@kamelsamer5768 the estimate for gold per kilogram is for either mixed bgas with some copper heat sync ones. (This was soo many if i recall) Or for no copper heat sink ones. The heat syncs are very heavy and skew the estimated gold recovery. Just something to keep in mind for those who may purchase or bid based apon an estimate they read.
