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.
Panning, in mining, simple method of separating particles of greater specific gravity (especially gold) from soil or gravels by washing in a pan with water. Panning is one of the principal techniques of the individual prospector for recovering gold and diamonds in placer (alluvial) deposits. The
Invention Store Physical Separation Of Gold. Solution. The present invention relates to a plant and a procedure for separating gold or other metal particles from a mixture of particles by applying dielectrophoresis. The physical separation method specifically separates metals Details
Steven Cochran''s answer to What is the chemical method used to refine gold? Now, if youre searching for how it is first separated from the rock, this is a simple explanation: When gold ore is dug out, the rocks crushed int small pieces, then ground down into finer pieces. This is treated with a cyanide solution to pull the gold into solution.

#173;Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals.
Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546BC). Material from Sardis (in modern Turkey) is evidence of the earliest use of gold and silver parting in the 6th century. Literary sources and the lack of physical evidence suggest that goldsilver parting was not practised before the mid first millennium BC.
Gold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.

#0183;#32;When gold is oxidized, gold cyano complex [Au(CN)2] is formed with the presence of cyanide [4, 5] . 4Au + 8CN + O2 + 2H2O #226; 4[Au(CN)2] + 4OH (1) 4Ag + 8CN + O2 + 2H2O #226; 4[Ag(CN)2] + 4OH (2) The rate of gold dissolution is controlled by a number of parameters including cyanide and oxygen concentration, pH/Eh, particle size, solidliquid interface, and temperature.

Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. 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

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
