Question In the recovery of iron from iron ore the reduction of the ore is actually accomplished by reactions involving carbon monoxide Use the following thermochemical equations to calculate ΔHf° for the reaction
·The process of extracting iron ore involves mining where large scale excavation is carried out to access the ore deposits deep within the earth Once the iron ore is extracted it undergoes a series of processing steps to remove impurities and prepare it for further use The first step in this process is crushing and grinding the ore to a fine
·Now let us turn to the step by step procedure of producing iron from its ore Pig Iron Pure iron is unavailable as mentioned earlier What you are most likely to get is a good supply of iron ore that can be converted into pig iron in a blast furnace Generally pig iron has a composition of 92 94% iron and the rest carbon along with other
·The schematic of the MOE process is shown in Fig et al [] used the MOE method to treat the raw materials of iron concentrate powder used in blast furnace smelting and analyzed the energy consumption of the MOE iron making et al [] produced metal iron and oxygen by performing electrolytic melting on a floating soil analog at 1600 °C
·Spectrophotometric Determination of Iron INTRODUCTION Many investigations of chemical species involve the interaction between light and matter One class of these investigations called absorbance spectrophotometry involves the transfer of energy from a photon of light to an analyte to produce an excited state species By accounting
·The third approach for the assessment of mineral resources involves the Second Law of Thermodynamics Valero and Valero established the concept of the exergy replacement cost ERC for the evaluation of mineral resources [66] [68] The ERC represents the energy needed to concentrate minerals at an average ore grade from Thanatia which is an ideal
