The gold will flatten and the MnO2 will spall off as a blue-black powder. MnO2 coated gold is uncommon except in a few localities. On some gold lease/claim there are the very occasional sample of MnO2 coating a piece of Gold. The way to find it is to notice when some black particle acts a bit too heavy in the pan to be Hematite or Magnetite.diergetos322.jpg" />

The black sand sample used in this study came from Vancouver, B.C. area and was concentrated from placer materials.

How to Extract Gold from Black Gold Sand?

Black sand has a specific gravity of from 5 to 11, or 5 to 11 times the weight of water. Gold, on the other hand, has a specific gravity of around 19 and platinum around 21. As you can see, gold and platinum can be two to three times the specific gravity of black sand, and this is why gold or platinum can be extracted from black sand ore.diergetos281.jpg" />

Liberating gold from black sand can be a very difficult process, especially when the gold is extremely fine. The finer the gold, the more difficult the recovery seems to be.
