IN THE MODE OF EXTRACTING PRECIOUS METALS,-GOLD SILVER PLATINUM, AND
COMMON METALS FROM SILICIOUS ALUMINIOUS AND OTHER SUBSTANCES AND IN
THE MODE OF MANUFACTURING ALUMINIUM AND ALUMINIUM BRONZE AND OTHER.
METAL ALLOYS."
This Invention has for its object the extraction and separation of precious and.
other metals in an improved manner from Silicious Aluminious and other
substances, alloys and metals, and in the application of the same process for obtaining
and manufacturing Aluminium and Aluminium bronze alloys from the aluminious
and other residues produced therefrom.
For obtaining precious metals from any substance or substances before mentioned
I first pulverize and then roast them with charcoal or any form of carbon, asphaltum
that may be suitable, the time required for roasting would be regulated by the
component parts contained in the mineral alloys or other substances being treated.
The roasting can be done on a large or small scale and in any known suitable form
of vessels, crucibles, hearths furnaces or ovens, In treating gold quartz the heating
does not require more than an hour and a greater heat. than a red heat may be
applied as required. Tin, Lead, Copper and Zinc ores or their tailings require about
two hours and no more than a red licat need be applied in roasting the saine.
Should these ores contain sulphur pyrites or other substances that may or can be
driven off by heat without affecting the residues, To be operated the roasting must
be continued until the sulphur pyrites or other substances are driven off or
nearly so.
When the roasting, of the minerals or substances, is completed, it is thrown red
hot into water, by preference cold well stirred and washed clean.
The minerals or substances being operated upon are then dried and mixed with
the following fluxes for smelting in proper quantities Soda ash Carbonate of Soda
"

page_text: on or Carbonate of Potash Borax or any other fluxes used or may be used for
smelting minerals such as Lime Salt Rock Salt Fluor Spar or any similar substanco
that will produce the same result or a mixture of same always having a certain
quantity of Soda ash or Potash or Caustic Alkali in the mixture of the fluxes used
to bring the Silica and Alumina chemically combined with the metals into a soluable
state, or materials containing the above.
It is important and necessary that the fluxes and the minerals should be used in a
fine powdered state well mixed and put by for a few days at least, or a few weeks
would bo better so that the fluxes and minerals or substances combine partly
chemically together before they are put in a furnace or crucible or any other
apparatus, the mass will then act less on the crucibles or furnaces than if the mass
were put direct in the furnace when first mixed.
The fluxes can be used raw to save expense or when mixed with materials and
olements not injurious to the smelting.
When thoroughly mixed and put by for some time tho mass is put in crucibles
furnaces ovens or hearths and white lient applied thereto and it will soon be found
in a melted condition the length of time will be estimated and fixed according to tho
component parts of the minerals or substances to be operated on. By theso means the
greater part of the metals in the substances are then chemically separated from
the silicious aluminious and other earthy substances injurious to the process.
.
When tho smelting is finished I add Zinc and Copper by preference to the
melted mass or any other combination of metallic substances that will produce
electricity, and stir up well with a view of causing this developement of electricity
.which facilitates further and completes the chemical separation of the metals from
the Silicious Aluminious and other earthy substances injurious to the process.
The smelting may be carried on in crucibles, furnaces, or any other apparatus
suitable for the process.
The metals are afterwards separated mechanically from the dross or slag by
washing the soluble matters out, Then I purify in the usual manner.
If the slag or dross after the metals have been extracted contain any alumina I
reduce said alumina into aluminium by carbon or add thereto a certain quantity of
metallic copper or substance containing copper or alloy of copper the quantity being
regulated by the amount of alumina ascertained to be in the slag or dross and again
bring it into a melted condition and well stirred up from time to time. The
or substance containing copper will then combine with the metal Aluminium in the 3
copper
Alumina after being in a melted condition for an hour more or less, Stirring the
mass up again several times, I thereby produce Aluminium Bronze of a better
quality than any at present known as it takes up all the gold platinum silver, and
other precious metals left in the slag or dross by the first process.
:
The metal is then mechanically separated from the dross and purified in the 4
usual manner;
