Pisolitic iron ores (aka channel iron deposits, CID) are a special case of transported pisolitic ferricrust that form an important resource of medium grade iron ore (57-60 wt% Fe) in the Pilbara Region of Western Australia. Apart from minor deposits in the northern Yilgarn Province of Western Australia, they have not been found elsewhere.

Effect of Raw Material Composition on the Sintering …
With an increase in the pisolitic iron ore in sintering, the productivity of sinter decreased by approximately 1. 3% on average for each 10mass% pisolitic ore increased. The decrement varied with the kinds of iron ores replaced by the pisolitic ore. Increasing the pisolitic ore required a higher coke rate and more moisture in raw mix.

Channel-iron deposits
Channel iron deposits, also known as pisolitic iron ore are a major source of cheap, high grade iron ore exploited primarily in the Pilbara and Murchison regions of Western Australia.. The ore bodies consist of nodules of hematite, limonite-goethite with some clay, sand and silt matrix. These nodules (pisolites) are concentrated into alluvial and elluvial washes leading from the …

Pilot-scale sintering studies and plant trials showed that sinter plant …

Iron ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "natural ore".
