Substance Chemical To Reduce Phosphorus In Iron Ore Selected Chronological Bibliography of Biology and A Selected Chronological Bibliography of Biology and Medicine Part I Ga 1809 Compiled by James Southworth Steen, Delta State University
Phosphorus can be removed from iron ore by very different routes of treatment. The genesis of the reserve, the mineralogy, the cost and sustainability define the technol ogy to be applied. The articles surveyed cite removal by physical processes (flotation and selective agglomeration), chemical (leaching), thermal and bioleaching processes.

The technology of direct reduction by adding sodium carbonate (Na2CO3) and magnetic separation was developed to treat Western Australian high phosphorus iron ore.
#0183;#32;Since it has been demonstrated in this study that phosphorus is somehow contained within the goethite structure it is likely that any method to substantially reduce the phosphorus content of the goethitic ore will require some sort of heat treatment and subsequent leaching in acid or caustic solution with minimal loss of iron units ( Gooden et al., 1974, Bensely and Rogers, 1987, Cheng et
Iron Ore. Major impurity elements in iron ore are silicon, aluminum, phosphorus, and sulfur Often, a chemical separation is the only method able to remove phosphorus from iron or Phosphorus can occur as phosphoruscontaining minerals (eg, apatite) and being finely dispersed in hematite in oolitic ironstones or in goethite in goethitehematite.
dephosphorization in highphosphorus iron ores. That said, as of now, research on highphosphorus iron ore direct reduction mechanisms focuses solely on raw ores.[11,12] Due to the complex nature of highphosphorus iron ore chemical composition and the complicated interactive relationships between gangue phases, it
#0183;#32;Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines. Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore
Substance Chemical To Reduce Phosphorus In Iron Ore The iron occur in femineral ores contains impurities of phosphorus, sulphur and high alkali as well as impregnations of waste produce a metallurgy treatable concentrate the ore has to be grind for mineral liberation, enriched for concentration and dewatered for transportation.
In iron ore mining, miner usually choose a complete iron ore crushing plant for metallurgy. Iron ore beneficiation process. Almost all of the iron ore that is mined is used for making steel. So we need the extraction of a pure metal from its ore. The extract the metal from ores, several physical and chemical methods are used.
Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Disclosed is a preparing method for direct reduced iron using low grade difficulttoreduce high phosphorus iron ore as raw materials. The preparing method includes crushing ferric oxide iron ore to a granularity of 01mm so as to produce iron ore fines; mixing the iron ore fines, pulverized coals and auxiliaries sufficiently in a ratio of (8084): (69) : (812) by mass percentage, to produce
High phosphorus (rephosphorized) steels. P is normally used as a strengthening agent in amounts up to about %. P is added in amounts up to % to cold rolled, motor lamination steels in order to reduce AC core loss during service.
