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.

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold
