structure. The basis of value is iron units and prices are quoted for ore of 51.50 percent iron with penalties for leaner ore and premiums for ore of higher iron content. In addition to the iron content, the percentage of phosphorous and the percentage of sulphur have much to do with the value and the desirability of an ore. An
The Itakpe iron ore has tolerable percentage of both sulphur and phosphorous in iron and steel making. The percentage acid gangue should be less than 3.5 %. In this iron ore deposit, materials deleterious to iron and steel production (such as sulphur, phosphorous and non-ferrous metals) are absent from the mineral matrix. The
The upgrade of iron content in the ore to 68.54% and the drastic reduction in phosphorous and sulphur contents has thus rendered the Koton Karfe iron ore suitable for use as a super concentrate for the Aladja steel plant direct reduction iron making process.
Karfe iron ore by acidic leaching and reported that the phosphorus content can be reduced by acidic leaching technique. Thomas and Yaro , worked on Koton-Karfe iron ore and concluded that the ore has iron content of 43.34% with low silica content of 10.14% and the major mineral phases of the ore are magnetite, siderite and goethite.
Iron ore deposits found in abundance in Nigeria, West Africa with up to 3 billion tonnes are in Nigerian states like Kaduna, Enugu, Kogi, Niger, Kwara, Bauchi and Zamfara.

The Itakpe iron ore deposit has a reserve of about 200 million tonnes with an average iron ore content of 36%. This has to be beneficiated at a rate of 8 million tonnes ... an appreciable percentage of Fe total. This Fe total in the gangue may come from magnetite in the ore, which was not effectively separated. Recall from the above
· Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur and phosphorus contents. In addition, the ore cannot be beneficiated easily like Itakpe and Oshokoshoko iron ores because of its texture. This work studied the beneficiation, dephosphorization and desulphurization of Agbaja iron ore.
of the iron ore rocks and mines contain sulfide minerals such as pyrite, chalcopyrite, arsenopyrite, etc. The sulfur content of iron ore concentrates is generally about 0.5% to 2%, and sometimes more than 0.7%, while the permitted limit of steel industries is 0.1% (Soltanmohammadi et al., 2011). Meanwhile, the percentage of sulfur increases

The source of the sulphur in these ore bodies is either from the magma itself or from the pre-existing rock where it was present as sulphate. The most common nickel mineral in these ores is pentlandite, (Ni,Fe) 9 S 8. The atomic ratio of nickel to iron in pentlandite ranges between 0.34 and 2.45. Most often, though, it is about 1.15.
