title = "Energy balance of the reduction process of iron-bearing waste materials",
abstract = " The metallurgical industry is a trade where large amounts of waste are generated, including mill scale and iron-bearing sludge, which in the reduction process can be a valuable raw material for the production of sponge iron. In this publication the energy balance for such a process has been prepared and it has been shown that the electrical energy flow necessary to carry out reduction of mill scale with a CO + H 2 gas solution is 17.48\% of the total energy stream supplied to the process. The highest value of the supplied energy stream is chemical energy brought with a reducing gas of approx. 71.65\%. The largest energy losses occur in gaseous products of reduction and constitute 57.15\% of the total energy flux of products. Raising the temperature of the reaction gas from 25°C to 300°C reduces the electricity consumption about 14\%. The determined energy losses to the environment are strongly dependent on the final design of the reactor for the reduction of iron-bearing materials.",
