The three most commonly used processes for gold ore separation are gravity separation, flotation and cyanidation. Among them, gravity separation is a commonly used process in placer gold mines, flotation is mostly used in rock gold mines, and cyanidation is suitable for refractory gold ores such as oxide ore and flotation concentrate.
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.
Situation 2 Crush using a jaw crusher, mill using a ball mill or hammer mill, and concentrate using a shaker table. We can get high recovery 90-95 of free milling gold to 325 mesh and recover to approximately 400 mesh, recovery tapers off the smaller you go and past 400 mesh is very difficult to recover via gravity in my opinion.

The gold dust particles are mostly granular or scale-like, and the particle size is usually 0.5 to 2 mm, but there are also gold particles weighing a few kilograms and more powdery to the naked eye. The fineness of the placer gold is usually 850-900, and the average specific gravity is 17.5-18.0. Gold dust is divided according to particle size
Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold Au melts at a temperature of 1,064 C 1,947 F. Its relatively high density 19.3 grams per cubic centimetre has made it amenable to recovery by placer mining and gravity concentration techniques.

In this process the ore is crushed to a powdery substance from which the gold can be extracted by gravity separation. The gold dust then goes into the cyanidation mill, where it is dissolved out into a solution the technique was pioneered by MacArthur and Forrest. ... The solution dissolves the gold and the remaining rock pulp is filtered off.

The blue bowl gold concentrator has been our best seller for fine gold recovery for many years. The Blue Bowl is available alone without pump kit, or you can add various accessories like leg levelers, 12volt 750gph pump kit, and classifier sieves. Note material should be screened down to at least 30 mesh for optimum separation of fine gold.
Gold on the other hand, has a density of 19.3 when pure. That difference is what makes all the gravity methods of capturing gold work whether its a simple pan, or a sluice box, dredge, dry washer, table or jig, that big difference in density is what makes working with placers pretty easy.

Gold is one of the heaviest minerals. When pure, it has a specific gravity of 19.3. Due to its weight, it can be panned because the Gold sinks to the bottom. In addition, it can be easily separated from other substances due to the weight differences. Gold is also the most malleable and ductile substance known.
Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide vat leaching mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.
