THE BROWN IRON ORES OF WEST-MIDDLE TENNESSEE By ERNEST F. BURCHARD INTRODUCTION A study of the brown iron ore deposits of west-middle Tennessee has been carried on recently under a cooperative agreement between the Tennessee State Geological Survey and the United States Geo logical : E.F. Burchard. Page - on the south side of Big Ivy creek, 3 miles above its mouth. It is on the northern slope of a hill, the summit of which is some feet above the level of Big Ivy creek. Two principal openings expose the ore bed in place, besides which there are a number of smaller pits scattered over the hillside. RI 19 / Maher, S.

Iron isn't the only element that displays , cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO.

Interest in the iron ore of the Western Highland Rim dates back to the s and even earlier in the eastern mountains. The commercially valuable iron ores were located in the valleys and mountains of East Tennessee and in Middle Tennessee and were processed in facilities that supplied mostly local and regional markets.
