Fine Gold Recovery. Separating Placer Gold Particles
Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold s, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.
PARTING: Separate Gold and Silver by MeltingCEMENTATIONPARTING BY USING SULPHIDE OF ANTIMONYPARTING BY MEANS OF SULPHURPARTING BY NITRIC ACIDTREATMENT OF THE GOLD RESIDUETREATMENT OF THE SILVER SOLUTIONCOMMON PARTING PROCESSIn this ancient and obsolete process, gold was freed from small quantities of silver, copper, c., contained in it. The method was mentioned by Pliny and described by Geber, who wrote in Arabic, probably in the eighth or ninth century; it is possibly still in use in some parts of the East and of South America. It consists in heating granulations of argentiferous gold mixed with a cement, consisting of two parts of brick-dust, or some similar material, and one of common salt, in pots of porous...

What are the chemical and physical separation
Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bowl spinning at high speed with water to fluidize the material, a shaking table or spirals.
Gold - CONCENTRATION OF MINERALS - Google Sites
The shape of the gold particles affects to the choice of method for gold separation. Gravity separation is better to recover gold particles of isometric shape. Flotation better to recover gold particles that have the shape of flakes and plates (floating gold).
What are the chemical or physical separation
Small scale jewellery workshops refine and recover gold by alloying it to 8 to 10 carat purity and then increasing surface area by dropping molten gold in a thin stream into a bucket of water to get gold beads or droplets and then using nitric acid to refine it.
