phosphorus problem in iron ore
The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.
Phosphorus is a problem in ironmaking feedstocks, as phosphorus in iron gives the metal undesirable properties. Some iron ore sources have significant levels of phosphate minerals that are difficult to remove, and so use of ore from these sources requires the iron and steel plants to remove the excess phosphorus from the molten metal.
The localization of economic sedimentary iron ore and phosphorite resources is discussed in comparative aspects. It is shown that the major economic resources of iron ore are hosted in Precambrian rocks, whereas the phosphorites are related to Upper Phanerozoic.

A Bessemer ore carrying 52% of iron must not have more than .052% of phosphorus and the sulphur should not exceed .04%. But since the presence of phosphorus in pig iron increases the fluidity and tends to make sound castings, ores high in phosphorus are used in making foundry pig iron.

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
Extracting iron from iron ore using a Blast Furnace. ... Removal of other elements: Elements like phosphorus and silicon react with the oxygen to form acidic oxides. These are removed using quicklime (calcium oxide) which is added to the furnace during the oxygen blow. ... Avoiding the pollution problems in the extraction of iron from the ore.
Phosphate mining also releases some of the naturally radioactive material found deep in Florida's soils. That's a risk. When reclamation doesn't work or when revegetation takes a long time, plant and animal communities can be lost or greatly reduced. Sometimes, the effects of phosphate mining aren't detectable — and that is the scariest risk ...
Oct 25, 2007· The iron and phosphorus relationship in the iron and phosphorite ores in Egypt is examined through previously published data. Although Fe- and P-rich sedimentary deposits are closely associated in the same geographic and geological setting in Egypt, no correlation is observed in the examined rocks between iron and phosphorus.
Sep 13, 2017· Beneficiation plant processing, which treats ore to make it more suitable for smelting, only works if the phosphorus mineral grains are bigger than a few micrometers in size. Often, phosphorus is so finely disseminated through iron ore that grinding and physically separating out the phosphorus minerals is impractical.
Abstract. The localization of economic sedimentary iron ore and phosphorite resources is discussed in comparative aspects. It is shown that the major economic resources of iron ore are hosted in Precambrian rocks, whereas the phosphorites are related to Upper Phanerozoic.
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
Phosphorus has been long recognized as an unwanted element in steelmaking, which should be kept as low as possible. In current study, bio-extraction of phosphorus from goethite ore by naturally existed alkaline-tolerant microorganisms was investigated.

iron ore during phosphorus removal for 10 weeks is presented in Figure 3. Figures 4(a) and (b) present the variation of the iron ore phosphorus content, the substrates pH and the log of density during phosphorus removal from Agbaja ore 1.00/0.50mm and 0.50/0.25mm, respectively for 10 weeks by B. subtilis. It is observed that a rapid phosphorus 1
Phosphate Ore a natural mineral formation that contains phosphorus and phosphorus compounds in such concentrations that make it technically and economically feasible to process the ore in order to obtain phosphorus-containing products, such as mineral fertilizers, phosphate mineral supplements, and phosphate salts, for various industries. The major ...
Jul 01, 2016· Ultimately, the aim is two-fold: firstly, to produce iron ore concentrates with market specifications, based on a biodesphosphorization process for high-phosphorus iron ore deposits that exist across Europe and worldwide, and secondly, to improve the economic competitiveness of marginal iron ore deposits by value-adding by-products and waste.
The 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% …
Phosphorus is the second most plentiful mineral in your body. The first is calcium. Your body needs phosphorus for many functions, such as filtering waste and repairing tissue and cells.
