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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Open-pit iron mining in the 21st century is an expensive proposition that uses explosives, computers, telecommunications equipment, immensely powerful machinery and huge quantities of energy to convert iron-bearing rock into marble-sized pellets of concentrated ore. To justify the huge investment in such machinery, the mines run 24-hours a day, seven days a week. When they need to cut ...
Iron ore slime is generated from mines during processing and washing of iron ore, and it is not considered for pelletizing due to its excessive fineness and high gangue content, despite its good green bonding property. Mill scale is generated from steel rolling mills and reheating furnaces; it has almost nil gangue content, but is not individually considered for pelletizing due to its poor ...
Unlike rod or ball mills, HPGRs reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other. There are no rods or balls that need replacing and it reduces energy consumption by about 40% for certain ore types, Breneman said. It also substantially reduces water consumption compared ...

All of the iron ore that is mined in the UP of Michigan and in northern Minnesota is moved out of the region as taconite pellets. Most of that moves via train cars and then via large ore freighters, such as the one shown below. Rail transport of taconite takes place from the Marquette range area (where it is mined) to either Escanaba or Marquette, where it is loaded onto freighters for shipping.

The bulk of Chinese iron ore consumption will come from medium-sized blast furnaces of between 2,000-4,000 m3 w.v. These blast furnaces are easier to control and operate and typically consume higher levels of pellet to support high productivities. We forecast a clear shift towards pellet in Chinese burdens as a result, with the BF pellet rate increasing from an average of 150 kg/thm in 2015 to ...
