Hello All,
I was recently processing some random pieces of gold scrap on piece of dental scrap, one gold ring and a pair of cuff links . I have waited on the dental scrap because I knew the contents of that material is always a weird . I inquarted my gold as I normally do. Once I got to the nitric treatments the material started leeching a yellow color , eventually it turned greenish. When it was all said and done my waste solution was a amber tea color.I managed to drop my gold and the yield was what I expected. Now I was left with this amber solution containing my silver. I was thinking I had some palladium or platinum in solution though I wasn’t seeing anything on my stannous test. I decided to use copper to see what dropped. I ended up with an almost black percipient, and a green solution. I washed my percipient and decided to dissolve some in nitric to see what it was composed of, the solution dissolved and was now a bright orange yellow, I did a few drop test one stannous, one with hydrochloric , obviously both showed silver no other color. So next I dropped silver in test solution completely with hydrochloric and tested the silver barren ( still yellow/orange)solution with stannous this time it just lost color and cleared up. So this post is getting long I don’t process platinum or palladium so I don’t keep any dmg on hand. So my question is if anyone has any ideas what I’m dealing with or how else to test it. I’m going to attach pictures if it lets me in order of the processing if it helps. Thanks in advance for your help. (Ps on pallet test are from left to right ammonia (just to see) next stannous with silver, next hydrochloric with silver, and last silver barren stannous.
