METAL OUTPUT

termed primary metals The United States Geological Sur
veys figures prepared by J. Dunlop showing the recovery
OF secondary "copper" ead znc tin and antimony
married the table below The inquiry by the survey does
not include the large quantity Of old and steel re-
melted neither does include the precious metals The guam
ty of aluminium castings returned to secondary shelters is al
so increasing rapidly condition for which the automobile
trade is largely responsible.
That the value OF the secondary metals exclusive of gold
silver platinum iron and aluminium should reach the large
tai value Of 1890 in year is fact not generally re-
allied except by those interested in the purchase Of metals
Though junk collectors and dealers pay prices for the
small quantities OF scrap metals the competition for the scrap

metals very active 1t necessary for employ
primary virgin pig metal but as general rule secondary
metals in whole part be used by manufacturers AS
they are frequently sold at slightly lower price than the prm
airy metals they in active demand and ispace an eov

secondary metal recovered from clean scrap made in the
binary of manufacture from those Of metal recovered
Dresses ashes and scrap that had entered trade in the
manufactured articles and been discarded
The table gives the quantity and value Of each secondary
metal recovered during the years 1910 1911 The largest
quantity and value the recovery of brass The
value OF the secondary tin much greater than in the
vlous year. owing part slight increase in quantity but
mainly to the higher selling price in 1911.
The total amount of secondary copper recovered on the
sumption that the brass remeed had average copper

manufacture OF copper and brass that only M
obtained from ashes cnde scrap and other material that
had actually been used and discarded While many of the
railways sell turn their brass and copper scrap to dealers
part payment for new material the reports received show
that the railways utilized in their shops and foundre
over l3OO tons of brass in addition to copper other alloys
The production of copper from secondary 1911
was equal to about 10 cent of the domestic output of
"copper".
The secondary lead recovered amounted TONS
Iabout 1000 tons less than in 1910 although the lead contained
alloys showed increase of 856 TONS The total output
secondary lead equal to Ill per of the refined lead
produced in the United States in 1911 compared with pei
cent in 1910 The lower percentage in 1911 caused main
by the increase OF over 10000 tons the primary lead yield
The output of secondary zinc (ncudng that in brass)
amounted 1887 tons and eqaed Psi per cent of the ota
production OF primary speter the United States in 1911 The
zinc recovered alloys other than brass amounted 1928

skmmings, ETC. In addition to the large quantity of speter
recovered several thousand tons of zine chloride made
from Dresses skimmings, etc
The production of secondary antimonv of which all but

None OF the regular smetes reported any production of anti
nony from secondary material solely The principal mater

deraby less in quantity than that recovered from secondary
sources indicating that secondary metals constitute the most
important domestic source of supply
AS the production of tin from mined in the United
States in 1911 confined to small of metal seted
in Texas and to the shipment of small yield of tin concen
rates from Alaska the secondary recoveres of tin form the
most important domestic of supply The secondary

ported into the United States during the year. The figures for
secondary recoveres in 1911 show increase of 8O3 in
quantity and $87 40 in value compared with the recoveres
