Iron Ore Deposits

Used earlier by the iron and steel industry, limonite and other East Texas iron ores have more recently been mined for use in preparing portland cement, as a weighing agent in well-drilling fluids, and in animal-feed supplements. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed.

What the heck is limonite?

Bacteria likely had a major roll in precipitating the iron oxides under these relatively stagnant conditions. Limonite forms from the alteration of other iron minerals such as siderite (iron carbonate), pyrite and marcasite (both iron sulfides.) Specimens of limonite after these minerals are relatively common.

Different Types of Iron Ore

The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.
