Iron Ore Pelletizing Process: An Overview, The iron ore pelletizing process consists of three main steps: 1 Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2The Making of Iron & Steel, Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agentProcesses and Procedures in the Extraction of Iron ,, The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyer Pelletizing Process, Iron ore must be shipped in bulk for maximum economy 12 Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process The pretreatment includes concentrating, dewatering, grinding, drying and prewetting In general, low-grade iron ore is ground into finesSmelting, Ramesh Singh, in Applied Welding Engineering (Second Edition), 2016 Smelting Smelting is an energy-intensive process used to refine an ore into usable metal Most ore deposits contain metals in the reacted or combined form Magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (αFeO[OH]), limonite (the generic formula for limonite is FeO[OH]nH 2 O), and siderite (FeCO 3) are iron ores, and ,.
