• TSHA Iron Ore Deposits

    When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed. The World War II demand for iron and steel stimulated production; small amounts of ore were mined until 1943, when more modern plants were constructed and production revived. According to the United States Bureau of Mines, in 1947 Texas
