what is limestone ore

    Creating Iron | HowStuffWorks, ­The more advanced way to smelt iron is in a blast furnace A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­) Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slagUses of Limestone, The use of limestone in steel making along with iron ore and coke is also quite popular In its pulverized form, it is used as a soil conditioner to neutralize highly acidic soil Additionally, the erosional landforms carved out of limestone rock, known as karst in geology, play an important role in natural landscapingLimestone and Dolomite and their Use in Iron and Steel ,, May 08, 2013· Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material The process of iron making is the reduction of iron ore ,Ironstone, Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron compound from which iron (Fe) can be smelted commercially This term is customarily restricted to hard coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian ageMining in Minnesota | Minnesota DNR, Minnesota is the largest producer of iron ore and taconite in the United Stat Even though nearly all of the high grade natural iron ore in Minnesota has already been mined, advances in technology have found a use for lower grade iron ore, called taconite , Granite and limestone are used in the construction of homes, buildings, roads and ,.
