CALCULATION OF BLAST FURNACE PARAMETERS
2020-4-17 · Equivalent amount CO from Fe2O3 of Mn ore Since Mn ore rate is 30 kg / thm and 25% of Fe2O3 is present in Mn ore So 30*0.025 = 7.5 kg of Fe2O3 in Mn ore. there fore oxygen needed to be gasify as CO = 7.5*(48/112)= 3.21kgs of O2. 3.21 kg of Oxygen will generate =3.21*1.25 =5.62 kg of CO
Chapter 6 Copper Production Technology
1996-11-20 · ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
Iron Age of civilisation: metal changes the world
2020-5-27 · Air was pumped into the furnaces with bellows. The early furnaces were cone-shaped and about one meter high. The lower part of the furnace had air nozzles through which air was supplied to burn coal. This created a very high temperature in the furnace, which made it possible to melt the charged mix of iron oxides and gangue.
Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of ...
