Removal of phosphorus from iron ores by chemical
高达10%返现Dec 01, 2006The results show that phosphorus occurring as apatite phase could be removed by alkali-leaching, but those occurring in the iron phase could not. Sulfuric acid is the most effective among the three kinds of acid. 91.61% phosphorus removal was attained with 1% sulfuric acid after leaching for 20 min at room temperature.

how to mines remove phosphorus from iron ore colombia
Oct 25, 2018Then, crosscurrent acid leaching was employed to remove phosphorus from high phosphorus iron ores in Wushan Mountain and the changes in dephosphorization ratio, iron loss and acid concentration was observed during the leaching. The results showed that the phosphorus in Wushan iron ores could be removed selectively by acid leaching.

Phosphorus Removal from Goethitic Iron Ore with a Low
Three West Australian high phosphorus iron ore fines (–6.3 mm) designated ore 1, ore 2 and ore 5 were used in this work. Ores 1 and 2 are examples of high phosphorus Brockman Iron Formation in the Pilbara and ore 5 was a high grade ore from within the Yilgarn Iron Province. Samples for the test

Selective Reduction of Iron and Phosphorus from Oolitic Ore
高达10%返现Nov 16, 2020The elimination of phosphorus from cast iron in ladles or steel-making units requires increased consumption of materials and time. The maximum phosphorus content in iron-ore concentrate for ore processing in a blast furnace is limited to 0.3 wt % by existing standards [1–5].

REMOVAL OF PHOSPHORUS THROUGH ROASTING OF
An efficient removal of phosphorus down to 0.05 % from high P iron ores is reported by Forssberg and Adolfson (1981). In this study P was also present mainly as apatite and its leaching was carried out with 2M HCl and 2 6 M HNO 3 at temperatures between 10 and 60°C and duration of up to 30 hours.

Dephosphorization of High-Phosphorus Iron Ore Using
Results show that the three strains of A. niger could grow well in the broth, and effectively remove phosphate from high-phosphorus iron ore during the experiments. Meanwhile, the total iron in the broth was also increased. Acidification of the broth seemed to be the major mechanism for the dephosphorization by these strains.

Characterisation of phosphorus and other impurities in
Nov 01, 2019Phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes, forming iron phosphides that make steel brittle. Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.07–0.08 wt-% P on the iron ore feed.
