Ironsand - Wikipedia

Akome ironsand is found mixed with sand made from an igneous rock called diorite. The magnetite in the sand contains often greater than 5% titanium dioxide, which lowers the smelting temperature. The akome ironsand is used in the tatara to make pig iron, which is then used to make items out of cast iron (nabegane).
