Fine gold can become black with a mold or allege growth on it. (look at the picture of my nugget of gold with the black growth on it.) The black sands can also be just like this nugget a lot of what you think is just black sand can be gold. So this is how you can recover it. Put all the black sands in a rock tumbler for a day or a few hours.

Rhodium DETECTION Rhodium is found only in platinum ores. It is a white metal, difficultly fusible, and insoluble in acids. Rhodium, however, dissolves in aqua regia when alloyed with platinum, to a cherry red solution. It is also soluble in molten phosphoric acid and dissolves when fused with acid potassium sulphate with the formation of K3Rh(SO2)3. If the metal is …
Black Sand contains many heavy materials including hematite, magnetite iron, iron pyrite, lead carbonates, sphalerite, chromite, and sheelite, to name the most common. There are many combinations of these as well as many others in small amounts specific to an area and too numerous to list. Suffice it to say, they are all black or grey in color and so are known …
Aqua regia is used to dissolve the gold into solution (the acids remove electrons from the gold atoms) and the gold forms a dissolved solution of yellow colored gold ions (a dissolved salt of gold), this also dissolve the very little metal impurity that the nitric could not get to, the nitric acid content of the aqua regia acts as an oxidizer ...
Save the black sand and gold concentrate in a container, ensuring it stays moist to prevent hardening. At the end of the prospecting season, use a blue bowl or other fine gold recovery equipment to separate the remaining black sand from the gold. This process involves careful screening and panning to remove finer particles and retain the gold.
This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a two-to-one ratio of acid to bleach. Ensure that the liquid mixture is at ...

If gold is physically bound to minerals, it can sometimes be separated by the application of heat in a smelting operation. At other times, the only way to separate the gold is to immerse quantities of black sand in …
No one in their right mind melts metals in metallic vessels (there are exceptions---lead and zinc, for example)---especially not gold in iron or steel. In spite of the fact that steel melts at a temperature roughly 1,000° higher than gold, molten gold is an extremely strong solvent, which will readily absorb your iron pan or steel vessel.

At no time did the magnet get closer than 3 ". The result was such that if you can imagine the results of when Dan just stuck the magnet into the pan, in his video, and pulled it out full of black sand with a little bit of trapped gold, exactly the opposite happened.

Gold is never lighter or the same weight as sand, gold no matter how small will have a density very much heavier. Pure gold has a density of 19.3 grams per cubic centimeter. Placer gold density can range from 15 to 19 grams per cubic centimeter. Black sand hematite or magnetite is around 5g/cm3.
