Copper Reduction Works at San Francisco.
We are informed that a company is perfecting organization for the purpose of
erecting copper reduction works at San
Francisco, probably in the vicinity of the
Dry Dock, at Hunter’s Point. As it is in
the metallurgical difficulty,—the economy
of reducing low-grade ores in this country,
where onr copper interests have met
their quietus, the new wet process of Bischoff promises something that we all hope
may be realized to the profit of the parties
concerned and the advaptage of the coast,
Similar works have been put up at Virginia
City to operate on transmontane copper
ores; but as that location is ata distance
from actual copper mines, and not in a center of easy natural communication, it is
presumed that the objects there were
mainly experimental.
Bischoff’s process is to roast copper sulphurets to such a stage of freedom from
sulphur and combination with oxygen, as
is recognized in the form of sulphate of
copper—chemically, nothing more nor less
than blue vitriol. Being theu soluble in
water, the sulphate of copper is leached
ont, and spongy metallic iron, prepared by
a peculiar process from black sand (magnetic iron), is thrown into the solutiov.
As the sulphur prefers izyon to copper, the
latter is dropped almost instantaneously,
falling to the bottom in the form of a red
metallic powder. Impuritiesin the copper
which result in the smelting product, are
here avoided, rendering the further refining of the copper to a marketable state
easy.
It is proposed to introduce the refined
copper so produced at once into the market
on this coast, Up to this time nll the copper used in the arts apd trades on the Pacific has been imported. It would seem,
certainly, in view of the demands of the
market, and of the many localities on the
coast where sure-producing copper mines
have been exploited past the experimental
stage, that copper reduction and copper
mining are worthy of further inquiry and
of careful attention by stock owners and
capitalists, who would profit from all that
has been tried and done in that direction.
Ponyrecunro Socrety.—A meeting was
held ou Thursday evening at the Committee
Rooms of the Mechanics’ Institute, by those
interested in the formation of a polytechnic
Society in conuection with the Institute.
The nnmber present showed the great interest taken in the subject by the members.
‘The President of the Institute, Mr. Hallidie, called the meeting to order, and H.
J. Holmes was elected Secretary, The
Chairman briefly stated the object in calliug the meeting, and called upon gentlemen
present to give their views. The aim and
scope of such polytechuic societies us those
connected with the American Institute at
New York, the Franklin Institute at Philadelphia, and the Polytechvic School of
London, were presented by different gentlemen. The agreement seemed general as
to the necessity for such an institution and
the desirableness of having it organized at
ence. Several gentleman spoke upon the
subject. On motiou acommittee of five
were named by the Chair, to report a plan
of organization and by-laws, on Tuesday,
Dec. 22d. On motion, the Chairman was
added to the committee. The Committee
stends as follows: A. S. Hallidie, W. F.

NUNGERFORD’S IMPROVED CONCENTRATOR,
For Saving Gold, Sulphurets, Quicksilver, ete.
Ie OTL
i
There is no deseription of machinory of so much importance to the mining interests of California, at the present time, as that for the separation of sulphurets. Many machiues have been tried,
and abandoned ; and none seems tn meet the requirement of the mining interest so well as that now
patented by Mr. Hungerford, which is au improvement on the well known Hungerford & Prater Conceutrator, with which his name is already so familiar.
RECOMMENDATIONS:
San Francisco, Octoher 19th, 1868.
Mr. M. Hoxeerrnrp—Dear Sir :-—We have had twelve of your Concentrators at work at the
Oneida Mine, Amador County, for about six months. They give entire satisfaction. They are
strong and snbstantial, requiring, thns far, no repairs, and do their work thoroughly and effectively.
Ata recent clean-up of four ot them, I found that in four wecks' timo we saved about $500 in free
gold, besides the sulphurets, or not far from one dollar per ton on the entire ernshing of the ten
stamps connected with them. In my opinion, it is for the interest of every quartz mill to have your
machines. Yours, respectfully, GEORGE PRINGLE, Supt. Oneida Miue.
Orrice oF THE OneIDA Mining Company, Jackson, May 13th 1868
Mr. Morgan Huxexxronp—Dear Sir-—In regard to the four Hungerford Concentrators that I bonght of Messrs. Goss & Lambard last month, I will say that I put them up in the
Oneida Mill soon after I arrived here, and find that they save sulphurets well and clean, and work to
my entire satisfaction. Ihave tried many nther concentrators, but these stand up and work better
than any others ] have used. I have ordered Messrs. Goss & Lambard to make eight more for me as
soon as possible. Very teuly yours, JAMES MORGAN.
Big Oax Frat, May 25th, 1868.—J/r. T. W. Mulford—DearSir:—I have used two of M. Hungerford’s Concentrators in tho Rattlesunke Quartz Mill, at this place, and find that they work full as
well as they are represented to do. E. M. SMITH, Supt.
A full description of tho principle and modo of action of this pan, is described in circulars, which
will be forwarded to any party who may desire them. 6
The Hungerford Concentrator has only to be seen to be appreciated. No millman will use any
other kind after ho has tried that. They are in activo operation in mills throughout tho State, and
Givo perfect satisfaction.
It should be borno in mind that Mr. Hungerford is the omginal builder and maker of the celebrated Prater Concentrator, and his name should bo sufficient guarantee to warrant the public in examining his new machine before purchasing elscwlicre. i .
In fntnre theso Pans will bo manufactured by Gopparp & Co., at tho Pacific Iron Works, San
Francisco, which is a guarantee that they will be built in tle most snbstantial manner.
Tbese Pans may boseen at the Pacific Iron Works, First street, near Iloward, San Francisco.
