Zinc and Copper Mining i'm New
UarSAV9

The Sussex Zinc and Copper Mining and Man.
ulacturing Company have obtained charter and
grant of about two hundred and forty of
and in the county of Sussex, New Jersey, about
ieen miles from the Morris Canal, near the town
Of Monroe, for mining purposes their grant COW
ers the most valuable and productive mines in This
country, and the only one in the world where the
red oxide of zinc is procured in sufficient quaint
ties for practical purposes. The locality has been
known for many years. 1t was opened by Lold
Stirling, who first opened the iron mines in Or
anre county, and constructed the first furnace
there He worked ii probably for the copper it
contained, so long ago thai now there are forest
trees foot in diameter growing on the debris
thrown out then. As zinc was an article not much
known al that time, and not In demand, the cop
per must have been the object.
About ten years ago the United States Govern
nen under advice, worked these mines to obtain
zinc to use in the composition of brass for the con-
slruclon OF the standard weights and measures of
The country. The zinc was known to be OF such
an excellent quality that it was procured without
regard to expense for the purpose above mentioned.
The present company, however, underline man
apement and direction of the most skilfnl chem
ISIS and mineralogsts, have at length succeeded in
bringing their plans to perfection, and in obtaining
all The valuable economic minerals that the local
iy affords. aa @
The mineral /" crops OUT at the summit Of
RIDGE that is preciptous on either side, and about
three-eighths of . mile in height The removal of
avery slight covering material lays open the ores
With this red oxide of zinc is found the mineral
called Franklinite, mingling chemically and me-
chanically. This Franklimte is species of iron
ore, which, as found here, yields iron the finest
quality, and fully eqoalinltenaeity and fineness 70
the Swedish, from which the English manufacture
their best steel. 1t is in veins from 8 to IS feet
vide and lies between two veins of secondary
limestone, The average depth ofwhich is reckoned
by geolosists at about 2,o0O feet.
Taxing the average. amount of ore, the zinc and
the iron are nearly equal insquantity. In some
veins the zinc predominates, and in other veins

Besides these valuable produetIons, the white
oxide Of zinc is manufactured also directly from
the ore in quality superior to any ever made. and
white aszthe whitest snoms vHhis forms one Ut the
best paints known, being entirely ffeelfrom all
posonous qualities, and remaining for years as
pure as when first put on. The French have
made use Of this oxide as a pigment but they
hare been obliged to. first manafacture the ore,
and reduce that to the white oxide at much great
er expense and without Obtaining SO pure an artl

has been produced by DIR Chiffon from this ore.

moderate red heat. when the red oxide becomes Of
the consistency OF paste and the metal is passed
through seiye and the zinc separated from the

is left at that stage is capable Of being used but
