Iron ore – Wikipedia, the free encyclopedia. This move follows a switch to indexbased quarterly pricing by the world's three largest iron ore miners . Bog ore often has a high phosphorus .
Iron Ore. The most important iron ores are the iron oxide minerals called hematite and magnetite. While many other minerals contain iron and can be mined such as the hydrated ore minerals limonite and goethite, and the iron carbonate mineral siderite the higher concentration of iron in magnetite and hematite make them the two preferred ore minerals.
In hematite and goethite ores, phosphorous tends to be dispersed and incorporated into the lattice of iron minerals. For example, more than 80% of Western Australian iron ore contains an average of % phosphorus . The phosphorus in Western Australian goethite ores occurs in the form of solid solution.
The most important deposits are at Grangsberg in Cen tral Sweden, where are specular hematite and magnetite ores containing 62 to 64 per cent iron and to per cent phosphorus, and at Gellivare, 100 miles from the Gulf of Bothnia, where are huge bodies of magnetite that run from iron and phosphorus to 60 per cent iron and per cent phosphorus.

Experimental research on a highphosphorus oolitic iron ore containing % iron and % phosphorus that had been treated by suspended flash magnetic roasting, indicated that a concentrate with an iron grade above 60% could be produced by LIMS, but the phosphorus content exceeded % [13,14,15]. Compared with the phases present in the original ore, a significant increase in iron content .
