Continue to heat the slag until you can observe the molten gold begin to dissolve away from the rest of the slag. This occurs because of the melting point and the density of the gold as compared with the different melting points and densities of the other metal components of the slag. The gold should slip down into the smelting vessel.
Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as quot;Cupellationquot;*. These processes are DANGEROUS and put the user at the

When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
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. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.
Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold in your
