Additives to Marra Mamba Iron Ore to Reduce Dust Emissions

Iron ore from the Marra Mamba Iron Formation of the northwest Pilbara region (Klein and Gole 1981) is mined by BHP. Marra Mamba iron ore is known for its ochreous or yellow-brown colour due to a high goethite content, and possesses a higher friability (ability to crumble) compared to other iron ore types (Lascelles 2000).
