Sir: We congratulate Dai et al. (2017) for their paper that provides age constraints and a model for the origin of banded iron formation (BIF)-related high-grade magnetite ores within the Anshan-Benxi area of the North China craton. Significantly, their contribution (1) highlights the potential relationship between Archean episodic crustal growth and BIF deposition in the North China craton ...
The textures of outcrop and near-surface exposures of the massive magnetite orebodies (>90 vol % magnetite) at the Plio-Pleistocene El Laco iron oxide-apatite (IOA) deposit in northern Chile are similar to basaltic lava flows and have compositions that overlap high- and low-temperature hydrothermal magnetite.
Iron ore concentrate (magnetite or hematite or their mixtures) and noncoking coal mixed in pellets are processed for 10 min by a single-stage heat treatment in an RHF, yielding high-quality (96–97% Fe), slag-free iron nuggets. These nuggets are easier to handle than DRI or hot-briquetted iron and are processed in EAF or (after remelting) in BOF.
Phosphorus Treatment and Removal Technologies. be in the range of 12 to 40 moles aluminum or iron per mole of phosphorus The pH value is an important factor for efficient removal of phosphorus using alum or other salts, as the solubility of their precipitates vary with pH Phosphorus removal is most efficient in the pH range of 5 to 7 for alum and of 65 to 75 for ferric salts since their
2015-4-1 Based on the results obtained, it can be concluded that most of Katse iron ores are of a high-grade magnetite and low hematite ore that can be profitably exploited for the production of iron. Iron ore from four locations contains more than 82% Fe. This compares well with other iron ores from the main iron ore producing nations.
Iron ore from five hills contains more than 67.0% Fe. This is regarded as high-grade iron ore and compares well with other iron ores from the main iron ore producing nations. The silica and alumina contents of these ores are also below 1.2% and 1.0%, respectively, with correspondingly low levels of S (<0.006%) and P (<0.05%).
Ukraine's total reserves of proved economically minable iron ore were officially estimated at 18.8 billion t (in 1968), constituting 32 percent of total Soviet reserves (21 percent of high-grade reserves), and an additional 7.2 billion t whose exploitation has yet to be assessed. There are 79 iron-ore
2021-6-1 The vanadium‑titanium magnetite with 67% passing 0.074 mm was taken from Chaoyang city, Liaoning province, China. The chemical compositions of vanadium‑titanium magnetite ore are presented in Table 1, which were determined by chemical methods combined with X-ray fluoroscopy (XRF).The vanadium‑titanium magnetite ore contained 47.58 wt% Fe, 20.00 wt% TiO 2 and 0.80 wt% V.
Prior oxidation of magnetite ore to Fe 2 O 3 leads to similar reduction behavior when compared with natural hematite; however, natural magnetite is hardly reducible due to low porosity and the formation of dense intermediate products during the reduction. 8) Accompanying oxides in the iron ore, such as alumina, influence the reduction
2021-9-9 Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

2019-7-16 Osaka - Magnetite (Fe 3 O 4) is best known as a magnetic iron ore, and is the source of lodestone. It also has potential as a high-temperature resistor in electronics. In
2019-11-27 2.1 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
