Of weed killer and distributed to east
ern and western railroads for use on
their rights Of way. The stock Of
domestic was small; in fact no more
than 200 tons Of refined arsenic was
on hand October 81.
During the hrst eleven months Of
the year 9,l6S short tons Of white
arsenic, valued at 81 .695. .654. was inn
ported. Most Of il came from Ger
many. Japan and Mexico, but some
came from France, Belgium, England.
China and Brazil. The imports Of
white arsenic at the eastern gulf and
lake ports exceeded those at ports on
the west coast. Notwithstanding the
prediction of brokers early IN the
year. high prices did not stimulate the
accumulation OF additional supplies
from foreign countries. Imports of
white arsenic sulphide amounted to
1886 short tons valued at $265, ,S61.
The total white arsenic bought for
consumption in 1923 from domestic
and foreign sources was about 1900
tons, less than one-third Of which was
made into calcium arsenic ard the
remainder was made into insecticides,
weed killer and cattle dip, or used BY
glass manufacturers.
Eight producers In the United
States reported the production of
arsenic. Three smelling companies
contributed 80 per cent Of the total
output Of arsenic. About half the
total domestic output was made from
charges Of regular furnace ore at
the smelters, and 20 per cent came
from arsenical ores and speiss pur-
chased. Nearly ten per cent of the
total came from two plants that treat
ore primarily for arsenic.
OF the arsenic contained in ore
smelted in blast furnaces, probably 25
to so per cent is saved. A larger re-
covery has been reported from plants
that use direct roasting where the
fume is caught in kitchens" and bag
houses. II the future demand for
arsenic warrants the expense Of equip
ment it may be found more preferable
to treat arsenic ores directly.
| No new discoveries Of arsenic ore
were made in 1928 and the most pro-
ductive sources were the mines Of
Gold Hill, Utah, Jardine, Montana, and
Eureka and Battle Mountain. Nevada.
The reserves of arsenical ores how.
ever, have been considerable increased
during the last year in Montana, Utah
and Nevada, and the development Of
arsenincal- properties in Colorado, So.
Dakota, Washington and California
may open up new sources Of arsenic
in 1924.
At Toulon. Nevada and Jardine.
Montana, two plants were operated
directly on arscnical ore and concent-
rate during the entire year. The re.
sidues left from roasting were shipped
TO smelters. Though these plants
were metallurgically successful and
probably profitable, their success has
not prompted the construction Of 9TH
er plants. At Martinez. California,
an arsenic plant was started late In
the year and some arsenical ore and
concentrate were shipped to It from
Nevada and the coast states.
The price of white arsenic an 1928
as quoted in journals published in
New York City ranged from 151a
cents a pound in January to 11x
cents Z pound in June and the latter
part of July. The lowest quotation
of the year was nine cents. Prices
improved as the larger consumers
commenced to buy, and Is cents per
pound was bid in November. Red a.
senic, which is all imported, was
quoted at IL to 16 cents a pound.
Metallic arsenic sold from % to As
cents pound.
