Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.

Compared with the rock gold, the method of extracting gold from sand is simpler. Gold sand mining and separation are usually carried out at the same time. The process of separating gold from sand mainly consists of four steps: crushing and screening, removing slime from gold sand, separation, thickening and dewatering stage. Step #1: …

At other times, the only way to separate the gold is to immerse quantities of black sand in chemical baths – a process called wet chemical extraction. The more complex the separation process, the higher the cost becomes of extracting each troy ounce of gold. Is It Worth Extracting Gold from Your Black Sand? Again, the answer is, it depends.

It will only be worth collecting gold from black sand if the cost of extracting it does not surpass the value of the gold itself. If only a small amount of gold is present in a large amount of black sand, it may not be worth trying to extract it. On the other hand, if a sizable amount of gold is present in the sand, and it can be separated ...

The process used for extraction requires the water to be mixed in the sand waste to make it into mud balls. The mud balls are then burnt with cow dung cakes at high temperatures after which the villagers cool them and take them to powder using machines. The powder is then put in a wooden vessel and mixed with rock salt and mercury.
