How Is Iron Extracted From the Earth? Reference
Mar 26, 2020 Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances21 Phosphate occurrences Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al, 2011)The most frequent and important constituent of the class of phosphates is Processes for phosphorus removal from iron ore a reviewThe present invention relates to a production method for dephosphorization and extracting iron from oolitic highphosphorus haematite Said method includes the following steps: uniformly mixing (by wt%) 60%90% of oolitic highphosphorus haematite powder, 8%20% of coke powder or coal powder and 020% of lime hydrate, briquetting or balling, drying, making reduction at 1100 degC1450 degC in CNA Dephosphorus iron extraction production
