  • Pyrometallurgical extraction of palladium from ceramic capacitors (MLCCs). Pd is recovered by smelting of the capacitors with lead and silver followed by cupellation. The resulting Pd-Ag alloy is then dissolved in nitric acid. Further palladium is refined and precipitated using formic acid.

      the weight of the beaker is 58.63 and the weight of the the beaker with the dried Pd powder inside is 60.56 from there you can get the weight of the Pd: 60.56 - 58.63 = 1.93g Pd

    Wait a minute now what kind of MLCCs are those exactly, they don't (from that first initial glance we were shown when you began to start incinerating them) I'm in the states. These appeared to be those other types of ceramic capacitors with two legs on them standing upright when mounted on a PCB. I'm accustomed seeing exceedingly tiny components that has the brown/light brown/dark brown/gray/white/and occasionally silver color tops with distinctive soldered ends at 2 sides, in the shape of being primarily rectangular, although square also exist.

      These are Eastern-Block produced high-performance MLCCs of the 1960s-1980s. The USSR had plenty of palladium available, so they used it to increase capacitor performance. As far as I know, Western capacitors didn't use palladium (at least as much as the soviets did).

      @@tylerbeyer4316 My knowledge, here, is purely theoretical, as I haven't yet done any of this stuff. I'm just paraphrasing things I've read at the goldrefiningforum, and I admit I may have a few details inaccurate, but:
      You can incinerate the mlccs without smelting into lead. But, then you should dissolve the base metals in HCL before moving on to nitric. The problem with this method is you then have to deal with ceramic dust clouding everything up and getting in the way of filtering.
      Smelting in lead eliminates that mess.

    Congratulations for the video, but if the pH reaches 7 or exceeds it begins to precipitate, along with the reduced metallic palladium, all the hydroxides of the base metals that the solution has as a contaminant.

    • @OwlTech333
      @OwlTech333  4 роки тому +4

      Not all but many, that's why pH 6 is somewhat critical - the Pd is precipitated with only a fraction of the silver
