LiquilyiDg Quartz.

Our readers will remember an extract
which we published short timesince from
an English Journal, stating that a new and
important method Of treating gold bearing
quartz, by solution, had been discovered.
By singular coincidence, this method has
been discovered in opposite portions Of the
world at the same time. Prof Hardinpe.
OF New fork, has made public his discove.
rv, which gives results so wonderful that.
were they not well authenticated. they
would be received with utter increduli,y.
By Prof Hardinge's method it is Claimed
that ton of quartz may be dissolved and
the metals disseminated in the rock all pre-.
clpltated 10y AN hours treatment; and that
the quartz solution thus obtained can be
moulded into any desirable shape for build
ing or ornamental purposes. The follow.
ing is the certificate of Prof Moffat, lalo
United States Assayis.;
have been for more than year inves.
tigating the philosophy Of dissolvng quartz,
according to the system adopted by Benja-
min llardinge, Esq. / have satisfied my.
self OF the practicabiity Of reducing quartz
rock to liquid as hmpid and clear as
pure spring water, by means OF b uinid heat
aud some simple solvents. and othet cbemi-
cal agents, at a very small expense. saw
hogsheads OF the liquid quartz at Mr.. Har-
dinge's promises. II was equal parts Of
water and stone, which fact was demonstras
ted by ptecipitating the quartz
In liquid state, If left to stand in els.
tern, all metals will fall to the bottom, by
which means every particle Of gold or other
metal may be obtained, and melted into
bars.
Cold quartz rocks, in many mines, are
known to contain from so TO 500 dollars
! per ton, and in some instances from one
thousand 10 five thousand dollars; which
may be obtained for a comparatively small
expense. Machinery may be erected for
from six to Ten thousand dollars that will
dissolve ten tons day; and the liquid
quartz, Will be source of more wealth to
the proprietors than the gold from ordinary
veins, tTo;a the many uses to which il may
be applied.
! have not only examined Mr.. Hardnge's
/ theory, out have witnessed many expert
ments by him i'll the presence Of other gen.
! tlemen, which were gratifying and conclu.
slve. have seen the complete analysis: on
| the one showing to our astonishmen: the
! quantity OF flint in solution, and have also
seen 1t perfectly sold6ed into colored glass.
have also seen Mr.. III. repeatedly change
the LIQUID flint into a semi.soid or plastic
state, and mould it into any form.
/ These and other suhsequental proofs, in
the strongest tests, confirmed me in the full
conviction that, by the working of his pa.
tents in California and in the Southern
States, every particle Of the gold can be OBJ
tanned from quartz; whereas by the old pro-
cess, now in use, not more than one fourth
of the gold is ever saved.

! The Importance Of such discovery as
the above, /! it I've fully substantiated, can
not be over estimated. Aside from the
prospect Of an increased production of the
/ precious metals, alone Of vast Importance,
IN view of The constantly increasing wants
/ of trade and the business world, its industri-
al bearing, il the economy Of tue process
be- stated truly, is one Of the greatest inter
est. Il beautifully cryetalized blocks Of
quartz can be afforded as cheap to the hand
! OF the mason as brick, where is the man
who would not prefer it as building
/ material. We look with interest for the
Development OF this proccss.--R Railroad
