Different Types of Iron Ore
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

What is the use of limestone in the iron and steel industry?
Answer (1 of 3): Having spent 40+ years as an iron- and steel-maker, I can answer this question. Limestone is used as a flux in the blast furnace. The limestone is added to the iron ore burden of the blast furnace in the amount of ~117kg per tonne of “hot metal” (steelmaker’s slang for the liqui...

Iron Ore Smelting Process
Limestone is used as a flux to separate the gangue from the molten iron ore, the accumulated slag and the molten iron being tapped from two tap-holes at the bottom of the furnace. The slag goes to a disposal area and the molten iron is directed into molds known as pigs where it solidifies to pig iron and is transferred to the next stage of processing.

Iron Ore (Iron Oxide) + Coking Coal (source of Carbon) + Limestone (reducing agent)=heat*=> Iron + CO 2 + slag. *for heating you can use other variety of coal / even electricity. #3: Near coastal areas. By early 20th century the coal and iron ore mines in US-Europe started getting depleted. So, they started importing iron ore from other countries.

Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface

Iron ore isn''t pure iron oxide – it also contains an assortment of rocky material. This wouldn''t melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide.

Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
