- quartz and goethite in iron ore deposite
The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay …

Australia, iron ore deposits are divided into three types: Channel Iron Deposits (CID), Detrital Iron Deposits (DID) and Bedded Iron Deposits (BID) that are banded iron formation (BIF)-hosted and result from an enrichment process. The BID are subdivided into two main types: (1) Hematite (martite-microplaty) and (2) Martite–goethite ores.
