The mixture of mercury and gold would then be recollected and heated until the mercury boiled away. A simple still like those used to make alcohol would draw away the vaporized mercury, possibly collecting it for reuse, leaving Extremely Fine Gold Recovery - Gold Recovery Methods · Devices such as a blue bowl, miners wheel, panning, even tabling, miss a significant amount of the gold (which can be recaptured by putting it back through the sluice). In many cases, the amount of ultra-fine gold captured by the sluice exceeds the visible large gold. This is of course no surprise, due to the fact that the majority of gold, at least where I am, is very fine gold. I think that Gold Extraction & Recovery ProcessesThe amalgamation of gold ores as described by Agricola in De Re Metallica is essentially the same as modern practice. The only changes are in the equipment employed and the sources of power to grind, mix, and separate. Probably, the chemical and physical processes are more clearly understood. Mercury is a heavy metal with specific gravity of 13.5, is liquid and boils at 357 o C. Its vapor Cyanide Use in Gold Mining - EarthworksA sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads.
