01.08.1982  Caustic extraction of the ash with sodium hydroxide was chosen as the beneficiation method to be tested, since it has been used for conventional iron ores (13). The silica and alumina in the ore react with the caustic to produce soluble sodium silicates and aluminates. Herzog and Backer (13) investigated the 234 beneficiation of low-grade iron ores by caustic extraction and found that an iron

Iron ore - Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.

ISO 2597-2:2008(en), Iron ores ? Determination

This part of ISO 2597 specifies two titrimetric methods, free from mercury pollution, for the determination of total iron content in iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chloride and titanium(III) chloride. The excess reductant is then oxidized by either dilute potassium dichromate (method 1) or perchloric acid (method 2).
