Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.
Iron and Steel Factsheet v.8 Columbia University. 2015-9-25 Emissions from BOF result directly from coke manufacture, used as a reducing agent to transform iron ore into the pig iron that is then turned into steel, the oxidization of coke/coal, calcination of carbonate fluxes, and from power consumption.7 The average total emissions intensity from BOF is 2.8 tCO 2 per ton of steel,
Cleveland-Cliffs produces environmentally friendly iron ore pellets and the feedstock that enables us and our customers to produce cleaner, more sustainable steel. Advancements in using direct reduced iron (DRI) and hot briquetted iron (HBI) in place of pig iron are further increasing productivity and reducing GHG emissions in steelmaking.
29-05-2019· The production of pig iron, which is later made into crude steel, uses iron ore as a basic material together with what is referred to as a reducing agent, which removes oxygen from the iron ore. Traditional pig iron manufacturing processes usually use coke as a reducing agent.
