Gold Price Charts in Any Currency

In addition to just examining gold price charts, you can also use the gold/silver ratio price chart. The gold/silver ratio is simply the amount of silver required to buy a single ounce of gold. For example, if gold is at $1200 per ounce and silver is at $15 per ounce, the ratio would be calculated as $1200/$15 = 80.

How Mercury & Gold Amalgamation Works

Sodium amalgam is used to revivify sickened mercury, or to maintain it in good condition. It is prepared by heating a basin or iron flask of mercury to about 300° F., and dropping in little pieces of sodium not larger than a pea, one by one. Each addition causes a slight explosion and a bright flash of flame.

Mercury Retort

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 ...

Mercury retort | Gold Refining & Metal Extraction Forum

Feb 25, 2007. Messages. 8,360. Jul 2, 2007. #4. A retort is nothing but a simple still. A chamber that is sealed, and can be heated, with an outlet tube that is cooled to condense the mercury. If you'd like, I may be able to provide a rather poor picture of the one I built many years ago. It's very simple in design, and worked well.
