How to Separate Gold and Black Sands - Gravity
2021-5-6 I discussed your question with one of my process colleagues in order to get his input on separation of gold from black sands. It can be difficult to get a good separation as the black sands are quite dense. This is even more apparent when dealing with coarse sand and fine gold. I believe the i150 will be setup to run at a maximum speed of 50Hz.

Gold Ore - an overview ScienceDirect Topics
Arsenical gold ores that do not contain significant base metals are treated using a bulk flotation method, where all the sulphides are first recovered into a bulk concentrate. In case the gold is contained either in pyrite or arsenopyrite, separation of pyrite and arsenopyrite is practiced. There are two commercial methods available.

extract gold from black gold ore -
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.
