The physics of the most common sedimentation process, the settling of solid particles from fluids, has long been known. The settling velocity equation formulated in 1851 by G.G. Stokes is the classic starting point for any discussion of the sedimentation process. Stokes showed that the terminal settling velocity of spheres in a fluid was inversely proportional to the fluid's viscosity and ...

How to Extract, Separate & Refine Gold | Sciencing. Separate the gold from unwanted rocks and minerals using one of several methods. You can mix the gold ore with sodium cyanide, which will attach itself to the gold and separate other elements such as zinc. Or pan the gold manually in water to separate gold from the gravel and sand in a stream.

Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold.

This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury. However, the use of mercury is very hazardous and mercury pollution in South American rivers following recent gold rushes has poisoned many indigenous inhabitants of the Amazon rainforest as well as the environment.

Jul 03, 2015· 3. Gold Cube – These separate out the gold in a very similar fashion as the sluices that are used in the beginning of the prospecting (if that is a prospectors method of choice) but these use smaller 'riffles' than a normal sluice does and there is also a lot less water used in the process. These are a more costly than some other methods ...

This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers ...
