Ceramic processor in AR
Boiled 3 ceramic processors in AR.
On addition of sodium sulfite to the solution.
Lots of blood red powder precipitated, there couldn't be that much gold in them. What is it ?
When all settles down, will try dissolving it in nitric.

This precipitate is just from washing a filter, after everything went through, there couldn't be that much gold!

Filter, dry, and weigh it. Sometimes precipitates are deceiving and look like more material than they really are.

I tried filtering gold from wash waters. It goes through the filter!!
You need to let it settle, and add all washes in to one. Then pour out or syphon out dirty solution, and wash gold with water and let it settle again
and like that many times. Then maybe coagulate it.

Ok, well then do that, then dry and weigh it
The fact that the precipitate is fine enough to go through your filter paper is further indication that it’s deceptively voluminous. There’s
probably less gold than you think there is.
