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 ...
phosphorus removal based on its as-beneficiated content, iron extraction rate and input concentration of H 2 O 2. Phosphorus present in the iron ore is locked up with the ore. During leaching of the iron ore in the required solutions, as phosphorus is being oxidized by oxygen produced from
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 present study is devoted to improvement of the leaching efficiency during phosphorous removal from high phosphorous gravity-magnetic concentrate.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Total Phosphorus (TP) removal under a variety of operating conditions is shown in Table 3.13.It can be seen that the bioreactor had a distinctive ability to remove TP, depending on the functions of BA fillers such as adsorption, chemical conversion, and microbe assimilation. The phosphorus accumulated in the reactor by adsorption and chemical conversion can be used to synthesize cellular ...

A model was derived for predictive analysis of the concentration of phosphorus removed during leaching of iron oxide ore in sulphuric acid solution [6]. The work indicated that phosphorus removal from the iron oxide ore as obtained from experiment and ...
Phosphorus Removal From Iron Ore. The ores which are mainly the oxides are reduced to iron with carbon with smaller quantities of silicon 1-3 manganese phosphorus and sulfur as impurities. reducing iron ore in the solid state and then hammering to remove the slag

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.

Table 1 shows the XRF results of the raw high phosphorus iron ore, solid obtained from the acid leach liquor by drying and crystallization, and iron ore residuals after acid leaching. It can be seen that the content of phosphorus in the iron ore decreased from 3.17% to 0.51% before and after acid leaching, respectively, meaning that it was effectively extracted into the acid leach liquor.

The phosphorus content in the DRI is still relative high even though there is no carbon in DRI, and it can be decreased to 0.087 wt% (raw ore 1.2 wt%) with the optimum condition in this study. It is proved that P exists in the DRI recovered from melt separation in the form of P 2 O 5 inclusions or Fe x P as solid solutions, while not in the form of Ca 3 (PO 4 ) 2 inclusions.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
