Cause the lab ground the sands to a powder then assayed for the gold. So in reality I don't know how much of the gold is trapped inside the larger black sands and how much of it is just very fine micro gold sitting freely in the black sands. I have not used a gold cube yet.

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.

If you live in an area with large deposits of black-colored sand, are you sitting on tons of gold that you can refine? Or if you work for a mining company that pulverizes minerals and ends up with quantities of black sand, it is likely to contain quantities of gold that are worth extracting?

And seeing all the exaggerations about "micron" gold in water, that come down the pike now and then, I'm cautious about the realities and occurance rates of the "black-gold sand" phenomenon. Sending black sand to a refiner that you didn't know well, would be about the most unpredictable way of recovering gold from it.

The black sands along the Mediterranean coast in Egypt account for a vast reserve of different beach sand minerals along with monazite. Moustafa and Abdelfattah ( 2010 ) have proposed a laboratory-scale beneficiation flowsheet to concentrate from the feed assaying 0.2% monazite, which is depicted in Fig. 2.4 .

Black sand concentrates are what you end up with after first processing of your gold bearing material. It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of 5.26, an iron mineral that is non-magnetic and Magnetite, Fe3o4, with a specific gravity of 5.20, is magnetic.

A method of selective gold recovery from black sands has been elaborated which is based on the liquid phase low temperature chlorination of materials. A liquid agent mixture of sulphur monochloride S2C12 and sulphur dichloride SC12 is used. This method ensures the gold extraction either in the state of AuC13.SC14 complex salt solution or as metal. The …
