How much material (clay with gold) are you working with as a batch. 1cup, 1 gal, 5gal, 1 ton? I would think that the clay is lighter in weight than the gold, unless the gold is flour or very fine particles. That being said, it may be possible to seperate the gold and clay by weight. I'll get back to you when I know what your working with.

This ancient Gold Refining method is one in that the nitre must be " projected " upon the gold just before it melts, as it has little effect on molten gold. The method is still in wide use.

Q. I am retired and am a recreational prospector with a small (3 in.) suction dredge and a creek with a little gold worth messing with.
