Process OuIdones T r.
The Washington correspondent of the
San Francisco Post furnishes description
OF another new process for working quartz.
According to the statement made the Fryer
process, for which so much is claimed, is
left entirely in the shade. The cost of this
new outfit, with royalty, will not exceed
$4,000, and the expense of working quartz
with it, is placed at not to exceed $3.50
per ton. The patent right belongs to q
firm of Philadelphia foundrymen. Like
the invention of Fryer, which remains q
sort OF Sibylline book to miners, this process
is asserted to save all the precious metals
in the rock worked. IL the problem of
working refractory quartz has been solved
SO triumphantly, the sooner myriad Of
these crushers and furnaces are at work in
our mines the better. There are multi
tudes of lodges that can be made to pay
largely under such conditions. Senator
Jones will visit Philadelphia this week to
witness it's workings. We append the
portion of the letter relating to this new
process: r.. Izaf .t.+r +,.a
| THE LIGHTNING AMALaAMAToR.
This is the name of new process for
crushing and treating all kinds OF ores, full
up to the assay, and at equitable prices.
The whole apparatus is very simple.
Broken rock of about the size of turkey
egg is put into crusher not larger than
an ordinary piano, and from 20 to 25 tons
is pulyerized as fine as flour daily. A
larger crusher, Of course, performs more
work. One man only is employed about
the entire crushing, from the time it is
dumped until required for
THE FURNACE.
This consists of cast iron column on
cylinder from is to 20 feet high. Tt is
divided into three compartments equi-
distant from each other by valves worked
with lever. Around this upright cylinder
| there is built q brick enclosure with an
aperture sufficiently large to admit of
blaze from bottom to top. A charge of ore
is placed in the top compartment of the
cylinder, and after remaining five minutes,
the first valve is turned and the charge
| drops in the compartment below; there it
meets with stronger heat ami volatilized
quicksilver. Ten minutes i'm this and it is
| dropped in the next lower compartment,
where it is subjected to white heat and
dropped in the bottom to cool. Being
thoroughly impregnated with quicksilver
it goes to tke amalgamating pans and in
four hours comes out bullion. The quick
silver is supplied from chamber at the
foot of the third compartment, and oppo-
site to the furnace which supplies the heat.
by the use of the valves the quicksilver is
all or nearly all saved.
THE COST.
It is said that the entire outfit as above
described, with privilege to work it, will
not exceed $4,000. Ponderous machinery,
batteries and concomitant expensive build
ings and employees are curtailed, saving al
most fiye-sixths of the present cost. The
patent for this invention was issued about
one year ago, but improvements have been
made and defects pointed out which estab-
fishes its utility beyond question. The diff
ferent ores from Virginia and North Caro-
lima mines are being tried every day with
success. Ores that would only yield from
| 81 to $40 per ton heretofore are by this
method increased to SEQ and $22. 1t is
| owned by the foundrymen, Walker s. Co.,
| of Philadelphia, and was discovered
| by the scientific representative of
that firm. The expense per ton is
not expected to exceed $3.50, and they
guarantee to get the full assay and in no
event to fall below five per cent. General
| Fremont has called Senator Jones' atten-
tion to it, and he will visit Philadelphia
next week to witness its workings. The
| above statement reads like fable, but we
have the authority to say that it is not ex-
aggerated. One is now being put down in
Virginia, on mine that would not be con-
sidered worth locating in either California
or Nevada, but by this saving it is a valua-
ble property.
The Fryer Process, which had obtained
favorable notoriety, simply occupies the
middle ground between this new method
and the old style. Mines that are not To-
| Gated on the bonanza range would do
we'll to send practical man here to inves-
| tigate. Such mines as the St. Lawrence,
| st. Patrick. Quadrille, Consolidated and
Greer, in Placer county alone, wauld rank
well as an investment instead of an expert
ment, if this process be true. Your cores
pondent accompanies the party to Philadel-
phia, and will then have more facts to speak
from. AS partial as this may seem, it is
asserted that they will even exceed what
has already been said. The old excuse
about not having secured their foreign pat
ents causes them to Withhold information
from the press, but the above brief descrip-
ton is all there is Of it. There is this in its
| favor, there is no acids nor secrets. It's SIM
plicity is what they desire to conceal, and
not the mysterious formula.-Nsuada State
