How to eliminate borax flux on gold, silver and palladium …

I tried to clean borax from gold in warm diluted sulphuric acid and the borax turned milky but still was stuck to the gold. I then put it in a test tube with 50% nitric and heated it with a hot air gun. It cleaned the button beautifully. No borax left and a nice shine to it. That obviously would not work on silver or palladium.

Need some info about borax for flux | Gold Refining

If I'm understanding it correctly, you never truly refined the gold. Fellow members have advised you about thinning the borax encased gold so you can pour off the extra flux and lift the gold button out before the remaining flux solidifies. Giving the gold button a boil in dilute sulfuric acid. that will dissolve borax that remains on your gold.

I think you might be mistaking the process. Use the borax sparingly to just precoat the melting dish, then put your gold powder into the melting dish, and begin heating. If you still have issues with the borax adhereing to the gold, a drop in some room temp water while the gold is still hot should shock the silicates off from your nugget.
