In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

GRAVITY SEPARATION This method of gold recovery has been practised for over 4,000 years, and was the only method of separating gold from its natural environment until the late 19th century. Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced

Mineral Processing If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation. This relies on the difference

Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore. When panning for gold you put your crushed gold ore in a wide pan and then add water to it. You then swirl the pan around with the aim of removing the lighter materials along with the water.

Now, for a gold pan, a very good panner can take a pan with 15 pounds of ore in it and pan it in 10 minutes. That is 1.5 pounds per minute, versus 100 pounds in 7 minutes, or 14.3 pounds per minute. The table is 10 times faster than a gold pan using theoretical situations. In reality it is more like 20-30 times more efficient than a gold pan.

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
