metallurgical testing for iron orefor the iron ore exploration and mining industries, sgs minerals services provides a comprehensive range of metallurgical testwork services. our extensive global network of laboratory and metallurgical testing facilities support most of the processes that are used in the exploration and treatment of iron ore. at the broadest level, these include: processes for phosphorus removal from iron ore2.1 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). standard test method for determination of phosphorus in iron 1.1 this test method covers the determination of phosphorus in iron ores, concentrates, and agglomerates in the range from 0.005 % to 1.0 % phosphorus. 1.2 the values stated in si units are to be regarded as standard. froth flotation of iron oresin general, phosphorus is considered as a gangue mineral in iron ore because it makes steel brittle. high levels of phosphorus in iron ore attract a penalty and reduces the profit margin substantially[42]. the mineralogy of phosphorus in iron ore depends on the type of iron minerals. different types of iron orephosphorus in steel makes it brittle. for steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called bessemer limit. a bessemer ore carrying 52% of iron must not have more than .052% of phosphorus and the sulphur should not exceed .04%. beneficiation of oolitic iron oresmineral processing of the ore to generate a commercial iron ore concentrate is very challenging due to the nature of these ores. accordingly, hatch and ironstone are developing a new pyrometallurgical process (hatch ironstone chloride segregation) to produce metallic iron from high silica and high phosphorus oolitic iron ores. the phosphorous issue at the agbaja iron ore project in nigeria successfully demonstrated prereduction of ore and smelting to produce pig iron with 98% fe is achievable phosphorus and carbon predominantly reported to alloy during smelting and constituted the major impurities in the crude pig iron removal of phosphorus from iron ores by chemical leaching alkali-leaching and acid-leaching were proposed for the dephosphorization of changde iron ore, which contains an average of 1.12% for phosphorus content. sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions.
