Determination of iron (II) by permanganate titration
Their presence is detrimental to the analysis results in two ways. First, iron (III) chloride complexes are yellow, and they can make it difficult to spot end point. To avoid the problem we can add phosphoric acid to the solution. Phosphate complex has higher stability constant and is colorless. Second, permanganate is strong enough to oxidize chlorides to free chlorine. While this process is ...
Iron Ore – MSK
Iron Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as "natural ore" or "direct shipping ore", meaning that those can be fed directly into ironmaking blast furnaces.

Iron Ore Statistics and Information
Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...

Direct Reduced Iron (DRI)
Directreduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.
