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

Feb 02, 2019 Iron ores with phosphorus content lower than 0.07% P are commercially desired as they are suitable for use in iron production. As a consequence, a lot of research efforts have been focused on phosphorus removal from high-phosphorus iron ore [20, 24, 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48] in a bid to reduce the P content to acceptable

Sep 01, 2020 As confirmed in Fig. 4, the aluminum occurrence changes with ore type whereas silicon mainly exists in quartz or kaolinite and iron mostly presents in hematite or goethite, which agrees with the results of Fig. 3. Aluminum in iron ore 1# dominantly occurs in alumogoethite while that in iron ores 2# and 7# are mainly in kaolinite and alumogeothite.

Jan 01, 2015 The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5)(OH) 4) and gibbsite (Al(OH) 3). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.

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 ...

Evidence for Surface Precipitation of Phosphate on Goethite
Recent studies have suggested that the interaction between phosphate and goethite includes ternary adsorption/surface precipitation as well as surface complex formation. The ternary adsorption/surface precipitation process envisioned involves the dissolution of the goethite crystal and subsequent adsorption of iron on the surface-bound phosphate. Further evidence to support the suggested ...

Iron ore - Wikipedia
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 ...
