Most likely, you dissolved all the metals in the CPU. That's a no, no. First, you must de-base the CPU's, then disolve the gold in AR, or HCI-CI...
Too much base metals in your AR makes it hard to drop the gold.

Try adjusting the ph.

Adjust the PH like above or put some zink in it and drop everything and start over with a new outlook. Or use some urea and then add SMB.
