Types of iron ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'highgrade' ore, and banded metasedimentary ironstone, magnetiterich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'lowgrade' ore.
