Gold from rock sample

This would work with very fine maybe 50 -100 mesh. Wouldnt work on anything larger. Great idea

If you have a larger quantity / courser black sands you would want to investigate using this method instead.

The black sand is turned into Glass and smashed away leaving just the gold.

you have to be careful with this method too ive found mate as black sand can create an environment where gold is burned off. I lost a little over a gram testing this theory was gutted
