One of the finest Halogen leaches applicable to extracting Precious
Metals, Iodine is selective to the higher valence metals without
adjustment, straight from the bottle.
Commonly available Iodine leach is sold as 7% solution, a remedy
for horses, cows and goats, as a disinfectant for Hoof problems.
Therefore it is found at Feed stores, Veterinary suppliers and some
True Value stores in Agricultural districts. If you cannot find it where you
live, please call us to order it.

Although not cheap, it has the virtue of being re-usable over and over, unlike the other
Halogens. Iodine does not wear out, and is only lost through evaporation and attrition. The
Iodine is dissolved in alcohol, which then makes it soluble in water. By itself, it is a black,
metallic-looking flake, and evaporates at room temperature.
Iodine leach, as sold, goes to work immediately on Gold, then Platinums, then Silver, in that
order. It tends to ignore the other "Trash" metals if used alone. Naturally, it is about PH 4-5,
and is kept there, especially in the presence of Alkali metals, by adding small amounts of
HCL acid.
ORP is not important here, as long as you keep the PH between 2 and 5 PH. It will naturally
begin at ORP 400 to extract metals.
As Iodine does not work as quickly as other leaches, patience is called for, typically 24-48
hours to collect fine gold.
It can be left to extract indefinitely, will not re-precipitate from solution, and will only stop
when the PH rises to 7.
The longer you let it leach, the more it will collect.
Let's Get some Precious Metal!
Start with a CLEAN plastic container (or Glass) of any size.
Make sure you have a tight-fitting lid for it after mixing the leach into your batch of ore.
Best results are obtained with the following formulation:
1 part 7% Iodine
10 parts water
1 part ore
10 parts combined liquid
Mix everything together in your container, making sure you have fresh air circulation, as
confined Iodine fumes can be toxic, and burn your eyes. For agitation, you can add a small
air bubbler with stone at the bottom of the leach tank, like those used in aquariums, to keep
the mixture circulating.
If you add heat to speed up the reaction, by quartz heater, keep the tank sealed during the
leaching, as it evaporates readily when exposed to air.
Your liquid leach will start out as a clear,brassy red color, and darken to brownish-rust color
or darker, as it collects metals.
Colors tell us what is going on in leaching.
Once you have mastered the routine, no meters will be needed to guide you, and the metals
are delivered.

* Owing to the many changes encountered in leaching procedures, and the advances made
in the process, we have finally published a straight-forward, easy-to-follow manual that
outlines each step, with plenty of pictures.
Outlined are all of the supplies and equipment you will need, where to get them and safety
procedures. Iodine is one of the finest Halogens for recovering Gold and Silver from
complexed ores.
We will also be consolidating other Leaching formulations into similar publications for
your library.
Thanks to all of you for your feedback, and hope you have enjoyed the many free postings
to help you find and recover Gold and it's friends.
