All of the above.<\/p>\n<p>During smelting, the fuel is burned to produce carbon dioxide. The carbon dioxide then reacts with carbon to form carbon monoxide. The carbon monoxide reacts with iron ore (Fe2O3) to form iron and liberate carbon dioxide.<\/p>\n<p>The overall reaction is:<\/p>\n<p>2Fe2O3 + 3C \u00e2\u0086\u0092 4Fe + 3CO2<\/p>\n<p>The smelting process is used to extract metals from their ores. The ore is heated in a furnace, and the metal is melted and separated from the ore. The most common smelting process is the blast furnace process, which is <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n              <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div>       <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> used to extract iron from iron ore.<\/p>\n<p>The blast furnace is a large, cylindrical furnace that is lined with firebrick. The furnace is filled with iron ore, coke (a fuel made from coal), and limestone. The coke is burned to produce carbon monoxide, which reacts with the iron ore to form iron. The limestone reacts with the impurities in the iron ore to form slag, which is a waste product that is removed from the furnace.<\/p>\n<p>The iron that is produced in the blast furnace is called pig iron. Pig iron is not pure iron, and it contains impurities such as carbon, silicon, and sulfur. Pig iron is used to make steel. Steel is made by melting pig iron and adding other elements, such as carbon, manganese, and chromium. The amount of each element that is added determines the properties of the steel.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[644],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>During smelting process, the combination of fuel in the furnace A.
