The purpose of a mercury retort is to separate the gold from the mercury components of the gold amalgam. By applying heat to the amalgam, the mercury is burnt off as a gas, which passes along the pipe to re-condense as a liquid. The gold remains in the distilling chamber of the retort, while the mercury is collected at the discharge end in ...

The retort is heated until it is dull red. It is now charged with the liquated zinc crust, which is broken or cut in pieces, or cubes of about 1 1/2 inches. Ordinarily a charge consists of from 250 to 400 lbs of alloy mixed with from 3 to 5 lbs. of small charcoal about bean …

Whereas gold melting is simply heating gold to turn into a liquid form before forming gold bars, smelting is a more complex process that involves the removal of impurities from gold using heat, pressure and a number of chemicals. History of Gold Smelting . The smelting of gold is not a new process. According to ancient literature, gold smelting ...

5. Place your gold and mercury amalgam into the lower cavity, and screw in into the upper part of the cavity securely. 6. Fill the water cup with 50/50 mix of water and antifreeze. 7. Wrap a piece of cotton cloth (making a tube) around the discharge end of the retort. Attach the cloth tube to the discharge tube with a rubber band.

DO store the retort it in a dedicated place - outside the house, and away from women and children. A retort MUST NOT be used by women or children. DO NOT store a retort and the clothes of the user indoors (unless it is a retort centre). DO NOT open a retort before it is completely cool to the touch, or mercury vapour will escape.

Gold Smelting Purpose of Smelting Smelting is the final stage in the production of tile gold. The purpose of smelting is to remove the metallic and other impurities into the slag phase, and produce a gold-silver bullion containing typically >95% precious metals.

Diagram showing how the mercury amalgam was boiled to separate the gold from the mercury. The mercury was collected for re-use. A mercury amalgam retort (a sturdy iron pot in which mercury-gold amalgam is boiled to separate the gold from the mercury) is sealed except for a pipe attached to the top of the retort.

Smelting gold is a popular choice for those with outdated gold jewelry that is mixed with other materials. Smelting gold is a technique for refining and shaping metals that has been in use for thousands of years. The discovery of this process marked the beginning of the Bronze Age as gold smelting was used for the creation of new weapons for war.

The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled. The anodes are approximately 99%

Gold content (oz/t) = gold weight (mg) x [29.166/sample weight (g)] Gold Refining Book. For example, if the fire assay reported 0.1 mg of gold and the initial weight of sample was 20 g, the gold content is 0.14583 oz/t or …

History. The smelting of gold began sometime around 6000 - 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold …
