Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron …

Limonite is an ore of iron and is used to make weapons and armor in the game. It has similar characteristics to other iron ores like Magnetite and Hematite. Although Limonite has low solid density compared to its brothers, the material has a very similar usage. Related: How to Mine Chalk in Dwarf Fortress

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bog-iron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.

Limonite Siderite Iron Ore Beneficiation. A laboratory mineral-dressing investigation was conducted by the Federal Bureau of Mines on four limonitic and four sideritic iron ores from the North Basin of the east Texas iron-ore district. The samples, composited from drill cores, were considered representative of the iron-ore reserves of …

Once you have managed to find a Limonite, use branching or veining patterns to mine more of them. Limonite ore is needed to make Iron bars, but you can also use Magnetite and Hematite. However, Limonite has a noticeably lower solid density at 7,850 units, which means it weighs less and can be hauled faster than the other two ores.
