Book Description
Excerpt from Mineral Resources of the United States, 1931, Vol. 1: Metals Except for gold 527 200) and a few mineral products of relatively minor importance representing a combined value 111 1931 of only $6, 500, 000 the downward trend in values was general. Com parisons of the various individual products show only a few scattered departures from this common tendency, and no notable increases were recorded. As in 1930, however, the intensity of the decline was far from uniform, and some branches of the mineral industry suffered much more than others. Among the metallic products, striking declines in values ranged from 44 to 54 per cent for the important industrial metals, copper, pig iron, lead, silver, and zinc, while the total value of metallic products decreased about 42 per Cent from that in 1930. Gold, the standard price of which was not affected by the business depression, again showed an increase in 1931 with a gain of per cent in output and value. Relatively large gains in the production of tungsten ores and chromite were accompanied by much smaller proportionate increases in values. The output of mercury and nickel gained about 16 and 21 per cent, respectively, but the total values were less than in the preceding year. These two products were the only ones except for gold, tungsten ores, uranium and vanadium ores, Orutile, and chromite (which enjoyed increased total realizations) in the entire metallic group to show value declines of less than 20 per cent. The mineral fuels as a group decreased about 32 per cent in value of total products. Less bituminous coal was produced in 1931 than in any year since 1909, and the anthracite output was smaller than in any year free from labor difficulties after 1900. Moreover, average unit realizations were slightly lower than in immediately preceding years. Petroleum output decreased for the second consecutive year after steady increases from 1925 to 1929, the output in 1931 dropped only 5 per cent below that in 1930, but the value declined about 49 per cent. Production of natural gas declined about 13 per cent and was accompanied by a sharp decline ln value, the output of natural gasoline fell about 17 per cent below that m 1930 and brought barely one half the total value reported for 1930.
