REMOVAL OF PHOSPHORUS THROUGH ROASTING OF OOLITIC IRON ORE WITH ALKALINE EARTH ADDITIVES Roasting, separation and leaching procedures The preliminary orientation tests have shown that during leaching with 096 M sulfuric acid at boiling temperature for one hour, about 33 % of the phosphorus can be removed
The iron occur in Fe-mineral ores contains impurities of Phosphorus, sulphur and high alkali as well as impregnations of waste rock To produce a metallurgy treatable concentrate the ore has to be grind for mineral liberation, enriched for concentration and dewatered for transportation
‘For example, in the iron and steel industry, the search for methods to neutralize the deleterious effects of phosphorous iron ore not only produced technological change, it also made the range of useable ore inputs endogenous’ , The correct spelling for the chemical element is phosphorus, while the adjective meaning ‘relating to or .
Iron is the second most abundant metal in the Earth's crust (after aluminium) and more iron is made than all the other metals put together The ores, which are mainly the oxides, are reduced to iron with carbon (coke) at high temperatures in a blast furnace
Phosphorus, however, remained a chemical curiosity until about a century later when it proved to be a component of bon Digestion of bones with nitric or sulfuric acid formed phosphoric acid, from which phosphorus could be distilled by heating with charcoal
221 Chemical Process Acid leaching has been considered as an alternative to flotation for removing phosphorus from iron ore Technologically, the leaching process is a simpler way to treat the fine-particle sinter feed without the restrictions that are necessary in flotation

The ore is loaded into a blast furnace along with measured quantities of coke and limestone Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron The slag and molten iron are tapped off from the bottom of the furnace, the slag being .
Froth Flotation of Iron Ores Mark Ma CSIRO Process Science and Engineering, Box 312, Clayton, Victoria, 3169, Australia Abstract 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
1 Introduction Phosphorus is a deleterious component in the iron-making industry, as it results in “cold shortness” of steel, and iron ores receive a price penalty if they exceed 007–008 wt% P (Cheng et al, 1999)At current mining rates, it is predicted that the premium-grade iron ore with low phosphorus will deplete within the next 30 years (Han et al, 2015)
