Jul 03, 2015#0183;#32;These captured gold particles are generally very small in nature and usually will consist of gold flakes or gold dust. Black sands are most typically made up of two types of crystalline iron oxides called magnetite and hematite. These black sands can pose a big problem when it comes to separating the gold from them.
Use a magnet to separate the magnetic black sands from these final concentrates. The magnetic black sands should be dropped onto another sheet of clean paper, spread out, and then gone through with the magnet at least one more time. The reason for this is that some gold can be carried off with the magnetic black sands. They tend to clump together.
magnetic black sands Gold Refining Forum. I have seen Magnetite grains cracked open with tiny globules of Gold imbedded in them, also Sulfides partially digested, again, with tiny particles of Gold. Every source is different and the Gold content may change in a distance of a few inches.
Use a 6inchsquare piece of window screen to sift out the fine particles, placing the dried sand on the screen and shaking lightly over a small bowl. Place the materials that did not pass through the screen on a piece of paper and use tweezers to remove larger gold particles from the materials that were too large to pass through the screen.
The trick is to make the magnetite and hematite jump up through the water to the magnet leaving the gold behind. Remove the black sand that sticks to the magnet and repeat. Eventually, when nearly all the magnetic minerals are removed, you can stir the magnet through the remaining sand in order to pick up as much of the material as possible.

Assuming your uncle is an amateur otherwise, he would be using industrial methods, the only safe way of extracting gold is by problem is that the gold dust is very fine, and may be too light to get trapped in a gold is a common misconception that gold panning was a primary method for obtaining gold from river deposits.
