Phosphorus
Phosphorus can reduce elemental iodine to hydroiodic acid, which is a reagent effective for reducing ephedrine or pseudoephedrine to methamphetamine For this reason, red and white phosphorus were designated by the United States Drug Enforcement Administration as List I precursor chemicals under 21 CFR 131002 effective on November 17, 2001...
Iron processing
Iron processing - Iron processing - The metal: Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to 45 percent carbon, 06 to 08 percent silicon, 003 percent sulfur, 07 to 08 percent manganese, and 015 percent phosphorus...

CN102212677A
The invention relates to a method for refining iron and removing phosphorus from complex refractory high-phosphorus iron ore, in particular to a method for sorting high-phosphorus iron ore by combining microwave reduction roasting and low intensity magnetic separation, and belongs to the technical field of mineral processing, particularly iron ore beneficiation...
Iron Ore Smelting Process
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 ....
Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15 Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on EarthIt has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 006 grams)...

Flux (metallurgy)
In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent Fluxes may have more than one function at a time They are used in both extractive metallurgy and metal joining Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus...
Different Types of Iron Ore
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgiteHematite is the most important iron ore...
Different Types of Iron Ore
A Bessemer ore carrying 52% of iron must not have more than 052% of phosphorus and the sulphur should not exceed 04% But since the presence of phosphorus in pig iron increases the fluidity and tends to make sound castings, ores high in phosphorus are used in making foundry pig iron...
The Extraction of Iron
Extracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat source...
Phosphorus distribution in BIF
Phosphorus is a deleterious element for the manufacture of steel The existing chemical processes to remove P from iron ores, the main raw material for steelmaking, are based on roasting and acid ....

Iron ore
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite Iron-ore mining methods vary by the type of ore being mined...
Iron Production
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue The iron found in iron ores are found in the form of iron oxid...
CN102559976A
Disclosed is a preparing method for direct reduced iron using low grade difficult-to-reduce high phosphorus iron ore as raw materials The preparing method includes crushing ferric oxide iron ore to a granularity of 0-1mm so as to produce iron ore fines; mixing the iron ore fines, pulverized coals and auxiliaries sufficiently in a ratio of (80-84): (6-9) : (8-12) by mass percentage, to produce ....
Processes for phosphorus removal from iron ore
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...
Commodities
Pure hematite mineral contains 699% iron whereas Magnetite mineral contains 724% of iron which is higher, but the presence of impurities on the latter results in lower ore grade, making more costly to produce concentrates that are used in steel smelters Used as a reduced agent in smelting iron ore in the blast furnace to produce pig iron ingot...
IRON AND STEEL
