Fluxed DRI[27, 28] This is a new type of DRI being developed containing lime Such DRI possess high degree of metallization together with crushing strength and weather resistant property for its prolonged storage in humid air This value added product is made by using fines of iron ore, coal, lime etc generated as waste in steel plants...
The very finely dispersed iron content, present as magnetite, is generally 25 to 30% In the late 19th and early 20th centuries, iron ore was of such high quality that taconite was considered an uneconomic waste product...
For iron ore mines, the stripping ratio ranges around 2-2515 This means that for every tonne of iron ore produced, double the quantity of waste is generated In 2003-04 itself, SAIL generated 476 million tonnes of overburden and rejects from its 12 mines in the country16...
