How is Iron Refined from Ore? (with pictures)

Iron ore consists of oxygen and iron atoms bonded together into molecules To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen To coax the oxygen atoms away from the ore requires14/03/2018· Six steps to process iron ore 1 Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage A static screen is used to divert the fine particles for crushing This step prevents overloading the crusher and increases its efficiency Fine particles make the crusher less efficient and increase the power draftThe Six Main Steps of Iron Ore Processing | Multotec Canada04/04/2012· Main component of BF slag is SiO 2 and Al 2 O 3, coming from iron ore as gangue minerals, and CaO added as a flux during sintering process On the other hand, BOF slag mainly contains CaO added as a refining agent, and SiO 2 and iron oxides produced by oxidation refining process The EAF slag is classified into two types, oxidation slag andIronmaking Process an overview | ScienceDirect Topics

How we make steel | British Steel

Coke, iron ore, sinter and limestone are fed – or charged – into the top of the furnaces A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron) The molten metal collects at the bottom of the furnace and the limestoneThe IFCON process, developed by ISCOR in South Africa, is capable of producing steel directly from coal and iron ore 1 In this process, coal and ore are added continuously to a channel type induction furnace containing a slagmetal bath Electrical energy is supplied by the induction furnace for heating and stirring the bath Oxygen is added for post combustion of hydrogen and carbon monoxideEmerging Technologies for Iron and SteelmakingFlash smelting Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfurcontaining ores including chalcopyrite The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore It has also been adapted for nickel and lead productionNickel: smelting, producingMetalpedia
