TIN 
brasses, solders, and bearing and type metals. A small amount also remained
in chemical compounds. Only about 11% of the recycled tin, mostly from new
tinplate scrap, found its way to market as metal. This latter volume provided
only 3% of the total tin supplied to U.S. consumers in 1972, a proportion
which does not vary appreciably from year to year. 
 Secondary tin furnishes 27 to 30% of the total U.S. tin supply each year.
However, secondary tin produced in this country was down in 1972 by 441 long
tons. 
 Five companies in 11 States were engaged in the detinning business in 1972.
Normally the raw materials used are tinplate scrap and spent chemicals or
tinning solutions.

CONSUMPTION 
Total consumption of tin metal decreased 1%, with primary tin consumption
increasing by 3% and secondary tin con- 
sumption decreasing by 14%. Tin used in solder, up 11% from 1971, was the
largest consuming sector in 1972. Although tin-
