The silver state. [volume] (Winnemucca, Nev.) 1909-1925, 1913-10-14
INCREASED Value
OF METAL OUTPUT

Metals produced from domestic ores,
foreign ores. matte and unrefned bull
lion smelted or refined in the United
States in 1912, according to a report
by J. P. Dunlop, of the United States
Geological Survey, have value of
1895, ,79s,6ls compared with $751;, ,727,-
776 In 1911.
The quantity and value of the metals
are given for both domestic and for
eign sources, but it is necessary to add
the value of the secondary metals re-
covered in 1912 in order to show the
vast extent of the refinery and smelt-
ing industry in the United States. AS
the value of these secondary metals,
which is exclusive of gold, silver,
ed to over $77,OOO,OO0 in 1912, it is
reasonable to assume that the total
value of the metals derived from for
eign and domestic sources by the
smelters and refneries in the United
States amounted to over $1,100,000,-
600. A portion of the increased value
in 1912 wah due to the much higher
average prices for silver, copper and
zine, but the production of all metals
other than gold and antimonial lead
increased in 1912.
The extremes in output are shown
by the fact that 1.3 tons of platinum,
1881 tons of gold and 4,471.4 tons of
silver were recovered from domestic
and foreign ores and from foreign
matte and unrefned bullion, while
the production Of pig iron, the largest
output of pig recorded in the United
States, amounted to 33,S02,685 short
tons. The yields of refined copper,
734,052 tons, and of spelter, 3S8,s06
tons, were also the largest ever made.
Increase in Iron and Aluminium.
The consumption of aluminium in
1912 was 32,803 short tons, an increase
of nearly 10000 tons over that of 1911.
Pig iron production increased over
7,750,000 short tons in quantity and
over 100000 in value. OF the pig
iron about 4 per cent was smelted
from foreign ores.
The production of zinc concentrates
in the central states amounted to 424,-
337 short tons in 1912, which came
mainly from ores mined in Missouri,
Wisconsin, Kansas and Oklahoma.
New Jersey was the largest producer
of zinc ores in the eastern states and
Colorado, Nevada, Utah, Montana and
New Mexico in the western states.
The production of silver ore given is
mainly that of silver-lead ores in
which the value of the silver exceeds
that of the gold. Pure silver ore is
very rare in the United States. OF the
1912 production, Nevada (mainly
Tonopah) is credited with 476,725
short tons, Colorado with 15S, ,429 tons,
New Mexico with 110,127 tons, Utah
with 1924 tons and Texas with 20,-
375 tons. The Colorado output is
largely n-manganese-s silver ore used
as flux in lead furnaces.
The production of lead ores in 1912
increased about 100000 tons compared
with 1911. The yield of lead concen-
trates from the central states (mainly
from Missouri) was 256,s3s short tons.
idaho, the largest producer in the
western states, contributed 176,704
tons.
The production of copper ores in
creased 100000 tons in 1912. The in
creases from the Lake Superior mines
and from Tennessee, while substan-
tial, were relatively small compared
with the largely increased tonnage of
copper ores treated in the western
states, amounting to over 100000
tons. New Mexico, Arizona and Neva-
da contributed the bulk of this in
crease, which consisted mainly of con-
