Pumping system design challenges for high-density iron

Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.

Australia’s Iron Ore Product Quality

2011-12-12  Channel Iron Deposit Channel Iron Deposits (Pisolites) are becoming an increasingly important iron resource with significant increases in EDR at Marillana and Yandi in 2008. Ore bodies are found in ancient paleochannels resulting in cemented masses of concretionary iron oxides of hematite to hematite-goethite composition (Hall et al. 1990).

2013-9-16  Channel iron deposits (CID) supply 40% of Australia's iron ore but their genesis is still the subject of debate. Two well-characterised samples of goethite/hematite CID from a diamond drill core in Mesa J of the Robe River area in Western Australia were dated using (U–Th)/He methods in order to constrain the timing of iron oxide formation and thereby provide a temporal context for CID genesis.

A Placer is a deposit of heavy minerals concentrated by mechanical means. A good example of this is in rivers and streams. Water, the mechanical mean, carries lots of sediment down the river channel. Gold drops out of the sediment load when the water slows down (around a bend or when the slope of the riverbed decreases) because it is so heavy.
