Mineralogy and genesis of rare Al-phosphate minerals in

Mar 01, 2020 Phosphorus is a major deleterious element in iron ore where it occurs as primary apatite in hypogene ore, and adsorbed into Mn-, Fe-hydroxides and forming secondary phosphates in supergene ore. Secondary phosphate minerals have been formed during a long history of weathering of itabirite and hypogene iron ore in the Quadrilátero Ferrífero (QF),

Characterisation of phosphorus and other impurities in

Nov 01, 2019 Phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes, forming iron phosphides that make steel brittle. Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.07–0.08 wt-% P on the iron ore feed.

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 particularly

Characterization by high performance liquid chromatography

The value of iron ore is adversely affected by phosphorus in concentrations over 0.03% by weight. The present research concerns the use of metabolic products of aPenicillium-like fungus to leach insoluble phosphates (hydroxyapatite) from ores. Ion chromatography was used to measure metabolism of glucose into acidic fragments. The rate and products of glucose degradation depended on both the
