Extraction of iron is lengthy process which commences from concentration through calcination roasting water and other volatile impurities like sulphur and carbonates are removed by the process of concentration the concentrated ore is blended with limestone caco 3 and coke and fed into blast furnace from the top extraction of iron happens. learn 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 liquid iron produced by the blast furnace). Archana 22 Feb Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag. 0 Comment 7 Ask a Question Practice Mock Test Aiims Sep 10, 2009What is limestone used for when extracting iron?

Limestone is added to remove acidic impurities forming a molten slag which floats on top of the iron. The carbon monoxide combines with oxygen from the iron ore to produce carbon dioxide. This is called OXIDATION. The carbon monoxide REDUCES the iron oxide in the ore, into molten iron which flows to the bottom of the furnace. Aug 25, 2017Let’s talk about Limestone. Limestone is a sedimentary rock and the leading stone extracted and processed in the United States. Out of all stone mining in the U.S., limestone accounts for roughly 42%.
