Hematite DSO is what Australia's iron ore industry was built upon. Karara, which at the time was a 50:50 joint venture between Perthbased Gindalbie Metals and China's Ansteel, some 200 km from Geraldton, was an entirely different operation. It comprised several huge grinding mills, magnetic separation units, tailings circuits, pipes going ...

The coarsegrained crystals of hematite, with a steelgray color and metallic luster, are known as specular iron ore. Thin scaly ores are known as micaceous hematite. Ruddle or red ochre refers to soft, finegrained, earthy crystals. Hematite is paramagnetic in nature, and has an opaque transparency and uneven fractures.
