Washoe Ores, Reduction Mills and Machinery.
Almarin B. Paul, an experienced and
well-known quartz operator in Nevada,
after giving an interesting review of the
mining history of Virgiuia City and viciuity, in the Evening Bulletin, closes with the
following :
As will be observed by the foregoing
tests, the surface ore of Gold Hill commenced with two-thirds gold and one-third
silver; this gradually changed iu depth,
and my last working on these ores rau dowu
to one-third gold in value to two-thirds
silver.
A BIT OF THEORY.
This creates a query, as yet never satisfactorily answered to my mind, and will no
doubt have to he propounded many times
before we can arrive at a solution that caunot he overthrown. It is presumed aud
generally acceded to, although some very
prominent geologists think not, that these
bodies of minefal are ejected from below.
But if so, how is it that the surface always
carries a higher percentage of gold, and
which loses itself as you descend in depth?
Are we sure that gold, through the action
of the sun’s heat in connection with atmosphoriec action and the other metals, is not
the product of silveras a base? As we are
all at sea in reference to the formation of
gold and silver, we can only suggest theories, noting Dr. Lanszweert, Daintree, and
others’ views.
A WORD ABOUT THE HOWLAND ROTARY
BATTERY,
I will now ask the attention of the reader,
if engaged in mining, toa few observations
respecting the Howland Rotary Battery, as
no act of mine in mining has been more
criticized than the adopting of these batteries in my Washoe operations. Their
adoption was no blind work, as I had used
them for three successive years previous,
and in no test with other mills was I beat
in returns. Jhad theu and have now great
faith in their principle. It certainly is in
the right direction. They will in time, I
am confident, become popular, especially
when introduced with the later improvements, on account of their simplicity, etticient working and cheapness.
SOME SUGGESTIVE FACTS.
They have now been running in the Gold
Hill mill of the Imperial Silver Mining
Company, for over seven years. As this
will be admitted by all to beagood test, we
will see how it figures up in the later years
as to yield per ton and wear and tear. To
get at it we will take the official reports of
the company for 1865, 1866, 1867, 1868. It
must he understood thatthe Imperial Comany have two mills, one of forty stamps,
etary) at Gold Hill, run by steam power,
and one of eighty stamps (straight batteries)
at Dayton, run by water power. The tests
I bring up are on ore from the same
mine—‘‘ Alta ”=-of which these mills have
worked thousands of tons within the time
named : :
1865—Gold Hill Mill, yield per ton.
1865—Reck Point Mil, “ *
1866—Gold Hii Mid,
1866—Rock Point Mill, « «
18¢7—Gold Hill Mil,“
1867—Rock Point Mill, ‘* 6 aoe
1868—Gold Hill Mil,
1868—Rock Point Mil, «
By this, it will be seen that, with the exceptions of the last year, the Gold Hill mill
had yielded a larger percentage per ton than
the Rock Point with all its modern improved amalgamating appliances, the former having the Knox pan, which was first
introduced when I built the mill.
So much for the yield per ton; now for
the wear and tear. The amouut of ore
worked during the foregoing year, was:
Rock Point mill, 95,312 tons; Gold Hill,
43,279 tons. The receipts for old iron during the same period, was: Rock Point mill,
$16,338.53; Gold Hill, $4,817.81. This
gives the wear and tear per ton of Rock
Poiut mill, 17 cents, and a fraction over,
per ton; Gold Hill, 11 cents, and a fraction
over, per ton; fractions being about equal.
These are undeniable facts, and will no
douht set quartz men, who are not governed
by prejudice, to thinking, as the saving of
mouey in the first investment, and being
daily benefitedin yield and wear and tear,
is an item they generally are ready to consider and accept.
TRO AND WOODEN BATTERIES,
Somehow in California there seems to be
an opinion that batteries constructed entirely of iron will not do, while in Europe
and America they ore superseding the
wooden ones. The only trouhle in the past
with us has becn that ali iron hatteries were
too lightly constructed, which proved misplaced economy. In localities where timber is poor or scarce, they certaiuly are
cheaper and more durahle. I might here
add that my expenses of working ores at
Gold Hill mill, from Ist of January, 1862,
to Ist July of same year, (being six months, )
was $1.52 per ton. Thisis the only working statistics J can now find among my
papers.
THE KNOX PAN.
As I have hefore ohserved, the pans for
amalgamating introduced into these mills
were those known as the Knox Pau. These
were originally got up for gold ores, and
this was their first introduction into silver
mining, and we may say the beginning of
the iron pan process of working silver ores,
unless we except the Hungarian bowl, or
the two foot Bartola pan as the origiual
pan. The Knox pan is fonr feet in
diameter, with iron mullers and copper
plated cross-hoards, aud is in an entirely
uew direction to either of the ahove. These
pans working so well, there was a general
desire to improve on them, which has culminated in more thau a dozen different
kinds, all of which are about the same
thiug, varying, however, in size, speed aud
power. For amalgamating slowly I think
Knox’s is preferable to all others. Waklie
made his five-feet diameter, which gained
some celebrity through the Smith and
Dewey process. These paus were set on
brick furnaces and heated by wood. Howland conceived the idea of a stove, as
cheaper and better (for the foundry).
They were made of iron, and beneath the
pan was a circular flue, in which the heat
and smoke cirevlated.
IMPROVEMENTS.
About this time Waklie, I helieve it was,
took up the idea of using steam directly in,
the pan (at Mexican Mill, Virginia, Nev.)
Howland caught at this idea and put steam
iustead of smoke into the iron chamhers
below the pan. About the same time Mr.
Palmer, of Palmer, Knox & Co., brought
out the false hatton with steam chambers;
and these are the steps, in order, which
have culminated in the Washoe Pan process, and the introductiou of the Varney
and Wheeler & Randal pans, which have
attained a great popularity from their pulverizing as well as amalgamating qualities,
THE GERMAN PLAN PREFERABLE.
Although the first, as I claim to be, to
launch out on this new line of working
silver ores, I nevertheless think it would
have been better for Washoe had the German mode been adopted. It would have
been going slower, to be sure (which does
not suit our active American blood), but
that is what we have got to learn in mining
land with it—not to expect too much ina
short time. We would have heen going
slower, as I before observed, but we would
have had 30 per cent. more bullion out for
circulation, or, tbe Comstock lode many
thousands of tons unextracted.
A FINAL SUGGESTION.
I don’t think it would hurt any of us
young American miners either if we would
set aside a little of our conceit, and study
Enropean and even Mexican modes more
than we do, especially the former. We act,
talk, write and think too much as though
there never was,any mining done until
California was discovered and Americans
went to mining. Idon’t think it would
hurt the shareholders of the Comstock to
reflect ou their losses, as on an average
40 per cent. of the Comstock metal is going
into the Carson river. The general idea is
that a School of Mines is going to remedy
all these evils. It may in years to come,
bnt there are auy numher of practical and
scientific miners in California obtainable at
fair salaries, who know more of metallurgy
and mining than a School of Mines can
teach new pupils in a quarter of a century.
Why not commence now if we want to
remedy evils by science? I do not wish to
he understood as being opposed to aSchool
of Mines—that would he absurd.
As Prof. Phillips has well observed:
Practice is as essential as science.
Creation or Man in Hawan.—The god
Kane drew his image on the sand, and called
it to life by the prayer oft repeated: ‘* #
hiki au e ola”—‘* Live through my power.”
It became a man named Aulihonua, or
‘“turning earthward,” as did the god when
drawing the figure. The man lived, and,
heing tired of his lonely life, besought the
god for companion. The light from the
heavens, Jani, cast lis shadow on the sand.
It became a woman, and she was named
Keakahulilani—“ Shadow looking heavenward” (for its source). These were the
aborigines of Oahu, theix names as above
being found in an old mele of the Oahu
chiefs.

An Opportunity for the Erection of
Tron Works.
In the development of the unmatched
resources of California, one of our faults
has heen to neglect what may he called the
sinews of our strength and wealth, for ohjects which glittered. Agriculture generally was deserted in early days for gold
digging, and now, iron, tin, grauite and
marhle are neglected for gold and silver.
This is wroug. We should not give any
one or two interests 2 monopoly of our attention and capital. In diversity of industry lies the greatest wealth and the greatest safety and strength. This, the history
of the richest countries of the world has
abundantly shown.
The fame of the wealth of the Sierra Nevada range in gold and silver deposits is
world-wide; but little comparatively is
known, because but little has been done to
show how rich they are in iron, marble,
granite, lime, copper, tin, and many other
valuable deposits. The first named—iron—
is the most requisite metal to commerce.
We use vast quautities of it, and enrich
those who produce it abroad, and those who
carry it to us from thence, evcry year.
This we need not do. Large deposits of
iron ore are found in many places in the
Sierras, notably at a point distant seven
miles from Tinker’s Station, on the Pacific
Railroad liue, above Cisco. This ore is of
the very best possihle kind, and without
selection or picking, yields, when smelted,
80 per cent. of pure iron, of a quality
which is suitable for steelmaking purposes.
The locality is thickly covered with timber,
and a really first ¢lass road connects it with
the railroad line. A trip to this place
would not cost over $50, and is one of the
pleasantest possible. The development of
this iron would hardly fail to be very profitable to our manufacturing interests, and
we think it would be wise for some of those
interested to visit the place and see for
themselves the advantages that are offered.
No speculators have possession of these
iron beds; they are open to the first parties
who vome along to work them in good faith.
The Pacific Railroad Company offers every
inducement to those who set about developing any of the rich resources along the
line of its road. Only half the usual
charges are levied upon the native products. The State of Nevada is a large consumer of iron, and the deposits named are
about 250 miles nearer to it than this city
is, whence our sister State receives her iron
supplies, The difference in freightcharges
would therefore constitute a handsome premium to the iron of the new district. Will
some of our iron merchants or foundrymen
look into this matter? There is both profit
to the individuals and the State in it.
