Hello everyone!
I completed my second batch of refining yesterday using This video.
My nitric acid (blue liquid) solution was blue but got cloudy and slightly darker towards the end. When I filtered it there was grey goo in my filter.
Note: I did not let it cook long enough for all of the base metals to dissolve. I got too excited.
When I did my water rinse and started with the muriatic acid/ aqua regia it turned green, but really dark green.
I knew something was wrong but I filtered (goo again) and added sodium bisulfite to the remaining liquid.
Nothing happened, no brown formed, I just ended up with the white shiny goo at the bottom.
The materials I used included pcb with tin, copper, silver, and other metals.
Where did I go wrong and how can I improve? I’m currently reading Hokes but I’m wondering if someone has gone through this and has a solution? Is the video I referenced missing important information?
How many degrees C am I supposed to heat each solution?
Please help.
