Gold testing using specific gravity

- the specific gravity method tells us whether gold is "about 20ct" or "about 22ct" but it''s not quite accurate enough to measure to the nearest 1ct. THE FOLLOWING TESTS WERE CARRIED OUT ON A PURE (.999 / 24ct) BAR OF GOLD, which we know, from the chart above, should read 19.3 .

Gravity Concentration

In the various gold rushes of the nineteenth century, many prospectors used gold panning as a means to make their fortune—another ancient method of gravity concentration. Gravity concentration, or density-based separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of low-grade ...

Gold panning

Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are ...

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.[1] Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
