The mine output of tin last year in the United States amounted to 109 long tons, whereas imports for consumption in this country were 49,009 tons. There was, however, secondary tin production from industrial scrap of 4300 long tons as a pure metal and 16,700 in alloy and chemicals, a total of 21,000.
The outlook for increasing materially either primary or secondary production of tin in this country is considered almost impossible. While there. are some tin ores in the United States and Alaska, they are of such low grade that they could nct be mined at a profit unless the price of.tin should advance considerably above present levels, it is estimated that at 50 cents a pound the potential output of tin would not be in excess of 310 tons yearly, while at $1 a pound a potential output of 3,000 tons yearly might be developed after three years,
