30/08/2022 · Ore deposits (contact metamorphism) 1. Contact Metasomatism • Contact metasomatism is a process of formation of new mineral by reaction between the contact rock and the escaping high temperature gaseous emanation with other important materials from the magma chamber. • For the deposit of this type, the magma must contain the ingredients of
For this process, coking coal is turned into coke, an almost pure form of carbon, which is used as the main fuel and reductant in a blast furnace. Typically, it takes tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of …
2022-06-05 · To make steel, iron ore is heated and melted in furnaces where the impurities are removed and carbon added. Today, most steel is made using one of two processes: Blast Furnace; Electric Arc Furnace (EAF) Blast furnaces use mainly raw materials (iron ore, limestone and coke) with some scrap steel to make steel, whereas Electric Arc Furnaces use mainly …

The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces.
The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots. MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual …
