ing 502 tons in the form of pig tin and 1,337 tons in the form of alloys
(mostly solder) made direct from the ores. In 1940 (revised figures), 1,391
tons were recovered—510 tons as pig and 881 as alloys. The total recovered
was 32 percent greater than in 1940, the production of pig tin being slightly
less while that of tin alloys increased 52 percent. The Government plant
at Texas City, Tex., did not begin producing pig tin fintil April 1942.
 The ores treated at domestic plants in 1941 were obtained chiefi from Latin
American countries, principally Bolivia, although sma quantities produced
by domestic mines were also purchased. Companies reporting the recovery of
tin from ores in 1941 include American Metal Co., American Smelting &
Refining Co., Franklin Smelting & Refining Co., Kansas City Smelting
Co., Metal & Thermit Corporation, Nassau Smelting & Refining Co.,
Phelps Dodge Refining Corporation, and Vulcan Detinning Co.

SECONDARY TIN

 Recovery of secondary tin established a new record in 1941, with a 27-percent
increase over 1940. The increase was due principally to greatly accelerated
industrial demand prompted by the national defense program and higher prices.
In appraising the significance of secondary tm as a factor m national supply,
it should be borne m mind that a very large proportion (approximately 80
percent in 1941) is contained in alloy scrap from which the tin seldom is
isolated but merely revolves in the various cycles of use, purification,
and re-i.ise of the alloys themselves.
 Secondary pig tin recovered by detinning plants in 1941 totaled. 4,500 tons
(3,700 tons in 1940), mostly from clean tin-plate scrap with only a small
tonnage (about 60 tons) from old tin-coated containers. Further details on
secondary tin are given in the chapter on Secondary Metals—Nonferrous.

CONSUMPTION

APPARENT CONSUMPTION

 The apparent consumption of primary pig tin is deter~nined by adding domestic
smelter production to net imports. As there was no recorded smelter output
from 1925 to 1939, inclusive, the apparent consumption for this period was
equivalent to net imports. The
