Key Data Set Information
Location CN
Reference year 2021
Name
Sinter ; sintering ; Sintering of iron ore
Use advice for data set When utilizing this LCA data set, it is important to accurately represent the energy consumption and emissions associated with the sintering process. Users should include all relevant inputs, such as ores, fuels, and fluxes, and outputs, including emissions to air and solid wastes. Care should be taken to ensure that the data is applicable to the technology and efficiency level of the specific sintering process used. If recycling of materials is considered, the data should properly reflect the net use of resources and resulting environmental impacts.
Technical purpose of product or process This sintering process is aimed at the production of sintered iron ore as a primary feedstock for blast furnaces in steelmaking. The high-quality sintered product is used in the iron and steel industry for efficient production and to enhance the metallurgical properties of the final output.
