Iron ore mining in Australia Part 1

Feb 03, 2021Australia has large reserves of pisolitic limonite ores, and the ore contains about 10% by weight combined water. Iron ore in Australia is mainly found in rocks that are more than 600 million years old. The mineralogy of iron ores in Australia is predominantly martite which is hematite that has replaced primary magnetite.
