IRON ORE, PIG IRON, FERRO-ALLOYS, AND STEEL 191
IRON-ORE MINING, BY STATES

 Alabama.—The production of iron ore in Alabama in 1932 was
* 1,374,534 gross tons (1,332,975 tons of hematite and 41,559 tons of brown
ore), a decrease of 62 percent from 1931. The hematite, much of which contains
enough lime to make it self-fluxing or nearly so, was produced at the Sloss
nos. 1 & 2, Raimund nos. 1 & 2, Red Mountain group, and Woodward
nos. 1 & 3 mines, all in Jefferson County. The iron content of that shipped
in 1932 ranged from 33.1 to 40.31 percent (natural) and averaged 37.19 percent;
the manganese content averaged 0.14 percent and the phosphorus content 0.31
percent. As in 1931, the Red Mountain group (819,299 tons) was the largest
producing mine in the United States. The brown ore was obtained chiefly from
the Russellvffle mine in Franklin County, the Tecumseh mine in Cherokee County,
and the Docray mine in Tuscaloosa County. The content (dried) averaged 50.7
percent iron, 0.75 percent manganese, and 0.62 percent phosphorus.
 Georgia.—Brown ore amounting to 925 gross tons was produced in Georgia
from the Tecumseh mine in Floyd County, Ga., and Cherokee County, Ala. The
ore averaged 50.5 percent iron (dried), 1.5 percent manganese, and 0.61 percent
phosphorus.
 Michigan.—Mining activity on the Michigan ranges in 1932 was again
sharply curtailed, as is shown by a production of 2,554,996 gross tons compared
with 7,552,581 tons in 1931. Of the 44 active mines in Michigan in 1932 (55
in 1931), only 6 (27 in 1931) yielded more than 100,000 tons each. The Norrie-Aurora
mine in Gogebic County again had the largest output of any mine in Michigan
in 1932—177,869 tons. The average production per mine in Michigan was
58,068 tons in 1932 compared with 137,320 tons in 1931.
 The ore reserves in Michigan on January 1, 1933, amounted to 164,632,117
gross tons, a decrease of 2,436,786 tons from the previous year.
 A report on the iron-ore mines of Michigan for 1932, published by the geological
survey division of the Michigan Department of Conservation,2 shows that the
average number of men employed per day was 3,529 (6,112 in 1931), the average
number of days worked 88 (170 in 1931), the average daily wage $4.294 ($4.~i63
in 1931), the average yearly earning $377.89 ($843.71 in 1931), and the average
tons of ore mined per man per day 4.06 (5.3 i~i 1931).
 The data in the following table on average per ton costs of mining ore at
underground mines have been abstracted from statistics published in much
greater detail by the geological survey division.
