occurance of phosphorus in iron ore

Processes for phosphorus removal from iron ore a review

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 phosphates is

Mode of occurrence of phosphorus in iron ores of eastern

Jun 30, 2011· The eastern limb of horse shoe shaped “Bonai Synclinorium” in India hosts Banded Iron Formations (BIFs), consisting of major high grade iron deposits. Phosphorus (P) gets adsorbed in the iron ore by way of ion exchange mechanism of clay minerals and hydrated secondary iron oxide minerals. Its concentration is lesser in hard ores and blue dust types of ores, while the highest in case

Characterisation of phosphorus and other impurities in

Nov 01, 2019· 1. Introduction. Australia’s iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).The phosphorus content of Australian iron ores is a

Phosphorus in Iron Ore from the Hamersley Iron Formations

The phosphorus content of the banded iron formation (BIF) and of the associated iron ore deposits in the north west of Western Australia is known to vary widely, a fact which has considerable econ~mic significance. Trendall and Blockley (1970) have described the variety of textural appearances of apatite in the Hamersley Group BlF, and suggest...

Mobilization of phosphorus from iron ore by the bacterium

Jan 01, 2009· The bacterium Burkholderia caribensis FeGL03, isolated from a Brazilian high-phosphorus iron ore, was used to mobilize the phosphate contained in the same ore. The phosphate-mobilizing ability of the organism was tested in shake-flask cultures containing sterilized crushed iron ore in a chemically-defined liquid culture medium containing glucose (1 g/l) as carbon source and no phosphorus

Iron–phosphorus relationship in the iron and phosphorite

Oct 25, 2007· The common occurrence of iron- and phosphorus-rich deposits in the geological record of Egypt that are formed in different settings offers an ideal opportunity to check the genetic relationship between iron and phosphorus and the validity of the FeP model to interpret the source and formation mechanisms of iron- and phosphorus-rich deposits in Egypt.

Phosphorus in different types of ore, sulfides in the iron

The Leveniemi iron ore occurs mainly in sedimentary rocks. In the coexisting iron-copper ore deposits at Tjaarrojaakka, high phosphorus contents are often found.In northern Sweden, there is also apatite enrichment in the ores and wall rocks which lie below the Kiruna-type

Mineralogy, geochemistry and the origin of high-phosphorus

Jan 01, 2017· The determination of concentration and mode of occurrence of phosphorus in the Aswan iron ores in the present study could provide a platform for designing physical, chemical and/or biological process(es) to minimize the phosphorus content in the ore and match the standard P 2 O 5 content in the iron and steel making industries.

Extraction of Iron from its ores, Iron dressing, Reduction

Oct 23, 2018· S + O 2 → SO 2. 4 P + 5 O 2 → 2 P 2 O 5. Roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus.. Roasting of iron is very important in the ore dressing process but this process pollutes the environment, Ore

Occurrence and Mineralogical Association of Phosphorus in

The various mechanisms by which phosphorus (P) occurs and is distributed within banded iron formations (BIF)-derived iron ore are examined. In unenriched, precursor BIF P occurs predominantly as discrete grains of primary apatite. In high-grade ores hosted mainly by the Brockman Iron Formation, P occurs in three main forms: 1. as secondary apatite; 2. other...
