By Keith Vining. Using textural classification systems to improve your business outcomes. After preferentially mining highgrade, lowphosphorus Brockman ore for some decades, Pilbara iron ore producers are now making the transition to increasing outputs of Marra Mamba (MM), Channel Iron Deposit (CID) and highphosphorus Brockman ores.

Ore Geology Reviews

analyses of magnetite bands indicated that the lowgrade iron ore from the Skelevatske–Magnetitove deposit was metamorphosed at T = ~530 °C. The metasomatic stage postdated and partially overla pped the metamorphic stage and led to the upgrade of iron quartzites to the highgrade iron ores.

The Geology and Genesis of HighGrade Hematite Iron Ore ...

The highgrade hematite deposits stand in contrast to martite–goethite ores which are generally accepted to be the result of supergene enrichment of ironformation because they are found along Cretaceous to Tertiary lateritic weathering profiles (Morris, 1980; Harmsworth et al, 1990).

At each processing hub – Newman, Yandi, Mining Area C and Jimblebar – the ore is crushed, beneficiated (where necessary) and blended to create highgrade hematite lump and fines products. Iron ore products are then transported along the Port Hedland–Newman Rail Line to the Finucane Island and Nelson Point port facilities at Port Hedland.
