Description
This dataset represents the national life cycle inventory (cradle-to-gate) of vanadium-titanium magnetite ore processed through beneficiation, from crushing to the production of hematite concentrate. It covers all activities associated with iron concentrate beneficiation production, but excludes the direct or indirect greenhouse gas emissions from the production of crushing equipment, magnetic separation equipment, personnel transportation, and daily office operations during the beneficiation process. The dataset was compiled from multiple data sources based on national standards such as the 'Manual of Production and Emission Coefficients for the Iron Ore Mining and Processing Industry (0810)', 'Emission standard of pollutants for mining and mineral procressing industry (GB 28661-2012)', 'Cleaning production standard Iron ore mining and mineral processing industry', and 'The norm of the energy consumption per unit product of iron ore dressing(GB31337-2014)', and is representative of the average production level of vanadium-titanium magnetite ore dressing across the country.
Activity Description
This dataset describes the beneficiation of vanadium-titanium magnetite ore nationwide. Magnetic separation is a primary technology in iron ore beneficiation across the country, particularly suitable for magnetite and vanadium-titanium magnetite. For non-magnetic or weakly magnetic ores such as hematite, limonite, and siderite, a combination of processes including roasting, gravity separation, high-intensity magnetic separation, and flotation is typically required to improve the yield and grade of iron concentrate.
The entire production process of iron ore beneficiation includes:
Crushing and grinding: crushing and finely grinding the ore to liberate iron minerals from gangue.
Magnetic separation (optional): using low- and high-intensity magnetic equipment to separate magnetic iron minerals (e.g., magnetite, hematite). Flotation and gravity separation (optional): For non-magnetic minerals or ores with high impurity content, further purification is carried out through flotation or gravity separation processes.
Screening and filtration (optional): Mineral particle size is controlled by screening, and water is removed by filtration to obtain high-grade iron concentrate.
Tailings management: Proper handling of tailings to minimize environmental impact.
Process Description
In this dataset, the grade of magnetite concentrate is 56.39%, which is the primary product of the mineral beneficiation process. The main component of magnetite concentrate is magnetite (Fe₃O₄). Due to its favorable magnetic properties, magnetite ore contains low levels of impurities such as silicon, phosphorus, and sulfur, with strict impurity control, making it suitable for use in steelmaking.
