Gold parting
Two technologies are dominant. They both start with relatively pure gold. • The Miller process affords gold up to 99.5% purity. The process involves blowing a stream of chlorine through molten gold. Impurities in the gold form chlorides, which form a slag that floats on the molten gold. • Invented by Emil Wohlwill in 1874, the Wohlwill process produces the highest purity gold (99.999%). It is an electrolytic process using pure gold for the cathode (or titanium a

Method of Gold Separation--1. Gravity Separation
Gravity separation is an ancient and the most commonly used gold enrichment method. Placer gold is usually showed a single native gold in the form, whose particle size is generally greater than 16 t/m3 having big density contrast with gangue. So the gravity separation is the most important method for placer gold beneficiation.

[method of gold separation and gold separation device]
A method of collecting gold by flowing water over a gold collecting medium located in a sluice to induce a positive surface charge on the gold collecting medium. Feeding gold laden material into the sluice with the flowing water to induce a negative surface charge on gold particles of the gold laden material and create a slurry. Setting the flow rate of the slurry into the sluice such that
