Auriferous and Argentiferous Materials.
We, FRANK TRICKETT, of Westcombe Park, in the County of Kent, Stone
Merchant, and JAMES NOAD, of East Ham, in the County of Essex, Electrician
and Engineer, do hereby declare the nature of our said invention, to be as follows:-
This Invention relates to an improved wet method of treatment of finely divided
auriferous and argentiferous ores and other materials for the extraction therefrom of
the contained float or other gold, silver and platinum.
In carrying the Invention into effect, we take about 12 parts of Chloride of Sodium
and about 1 part of Oxide of Manganese and make a saturated solution thereof with
about 24 parts of water, and decompose the same by means of an electric current,
continuing the application of such current until the whole of the Chlorine is liberated
and taken up by the solution, leaving a residue of Sodium Oxide.
The finely divided auriferous or argentiferous material is then put with the said
solution into a vessel formed of a non-conducting material, and steam or hot air is
driven upwardly through the solution to agitate and heat the contents of the vessel
for a sufficient time for the contained gold, silver and platinum to combine with the
chlorine of the solution, thus forming soluble chlorides of such metals.
Or such chlorides may be formed by boiling the said solution and auriferous or
argentiferous material together for a sufficient time.
For some of such materials it is not necessary to submit the said solution to heat as
aforesaid.
In other cases, such as in the treatment of pyrites, where the material contains
sulphur, such material is mixed with the said residue of Sodium oxide to facilitate
the removal of the contained sulphur before mixing it with the said Chlorine solution.
After such treatment, in any of such cases, the solution is left to settle, and as
soon as the solution is bright and clear it is drawn off into another vessel, also
formed of non-conducting material, and the settlement or residue in the first of the
said non-conducting vessels is agitated with water to wash out any remaining chlorides
of the said metals.

page_text: The bright solution is then treated for the soluble chlorides of the said metals
by being agitated with scrap zinc, scrap iron or any other suitable metal, adding to
the solution at times, if necessary, a small quantity of any acid most suitable for
precipitating the contained metal.
The precipitate thus obtained is then washed and refined in the ordinary way.

.Improvements in the Extraction of Gold, Silver, and Platinum from
Auriferous and Argentiferous Materials.
We, FRANK TRICKETT, of Westcombe Park, in the County of Kent, Stone
Merchant, and JAMES NOAD, of. East Ham, in the County of Essex, Electrician
and Engineer, do hereby declare the nature of the said Invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
This Invention relates to an improved wet method of treatment of finely divided

of the contained float or other gold, silver and platinum.

The precipitate thus obtained is then washed and refined in the ordinary way.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
The herein before described improvements in the extraction of gold, silver and
platinum from auriferous and argentiferous materials.
