pollution in addition to high operation cost. Bio-leaching is another method for removal of phosphorus from high phosphorus iron ores [17–19]. For example, more than 80% phosphorus was removed from iron ore containing 1.04% phosphorus after 21 days of leaching using sulfur-oxidizing bacteria with a particle size +0.074–0.1 mm.

The results indicated that when high-phosphorus iron ore concentrates containing 54.92 mass pct iron and 0.76 mass pct phosphorus were directly processed through acid leaching, iron ore ...
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 ...
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 …
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 particularly ...

In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.

The influence of microwave treatment on the liberation of iron ore from the high phosphorus oolitic iron ore from Aswan region, Egypt was studied. The effect of microwave power, exposure time and grain size on the liberation of iron ore was investigated. The microfractures and cracks of the samples were characterized before and after microwave treatments.
In this paper, the effect of reaction time, high phosphorus iron ore particle size, dephosphorization agent concentration, stirring strength (G), liquid- solid ratio (amount of leaching solution with differ- ent concentration/amount of iron ore, different liq- uid-solid ratios represent different addition of acid) and reaction temperature on ...
It is shown that iron ore concentrate, assaying 62.35 per cent Fe, and 0.20 per cent phosphorus content was manufactured at 90.54 per cent recovery of iron and 87.42 per cent of dephosphorisation ...
REMOVAL OF PHOSPHORUS THROUGH ROASTING OF OOLITIC IRON ORE WITH ALKALINE EARTH ADDITIVES . K Ionkov. 1, S Gaydardzhiev. 2, D Bastin. 3, A Correa de Araujo. 4. and M Lacoste. 5. ABSTRACT . The present study is devoted to improvement of the leaching efficiency during phosphorous removal from high phosphorous gravity-magnetic concentrate.
high phosphorus magnetite iron ore uses. 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).
High-pressure liquid chromatography analysis indicated that various organic acids were secreted in the broth, which caused a significant drop of the broth pH. Scanning electron microscopy of ore residues revealed that the high-phosphorus iron ore was obviously destroyed by the actions of these strains.
5/23/2013· Oolitic iron ore is one of the most important iron resources. This paper reports the recovery of iron from high phosphorus oolitic iron ore using coal-based reduction and magnetic separation. The influences of reduction temperature, reduction time, C/O mole ratio, and CaO content on the metallization degree and iron recovery were investigated in detail.
oolitic hematite ore, which has a special concentric and layered oolitic texture as well as high phosphorus content (0.4 mass%–1.8 mass%), is regarded as one of the most refractory iron ore resources.3–5) Besides, phosphorus is mainly in the form of apatite, where the particle size of the crystal is very fine and not easy to separate.
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 work were prepared by splitting representative ...

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening ...
