Hello

I joined the forum because I have been dealing with gold for nearly a year and I'm always running out of the way.
When I add Urea and, finally, the SMB, at the bottom of the mud amateus, white ,, crystals ,,

Where do I break?
many thx

In my experience,adding too much urea can cause this problems.

Yep looks like urea. The solution was probably left in a cold room.
After you do your water washes and hcl washes it will dissolve.

This is urea nitrate. Separate/skim the crystals or add water and use the liquid part

And start using sulfamic acid to get rid of the excess free nitric.
