Hi, we have Merrill-Crowe Process and we refine the gold precipitate with induction furnace. We use;
40% Borax, 30% Nitre,15% silica
We have many problems with the stability of slags, after just one hour in induction furnace, we have a foamy slag effect and it's uncontrollable.
do you have some solutions ?
I checked in old topics of this forum and We not find nothing.
Thank you for your help.
