This was the only tin smelter in the United States and played a significant part in the second world war. Well, according to the Americans anyway.
An estract from Wiki, Texas although for a far better history see the link. The archive photos don't name the smelter but as there was only one......
By 1939 the population of Texas City had increased to 5,200. The United States commitment to the war in 1941 furthered the boom in Texas City, propelling it into fourth position among Texas ports. During the war, Texas City experienced remarkable growth. Since the Axis threatened England and Holland , the only two sources of tin smelting in the world, the Defense Plant Corporation under Jesse H. Jones decided in 1940 to build a tin smelter in the United States. On a site donated by the Texas City Terminal Railway Company, the Tin Processing Corporation began operation of the only smelter in the western hemisphere. The Longhorn Tin Smelting Company supplied all the industrial and military needs of the free world. By 1950 the population of Texas City was estimated at 16,620.
