Description
This dataset represents the processing of vanadium-titanium magnetite ore through mineral beneficiation in Sichuan, covering the life cycle inventory (cradle-to-gate) from crushing to the production of titanium concentrate. It includes all activities associated with iron concentrate beneficiation production, but excludes direct or indirect greenhouse gas emissions from the production of crushing equipment, magnetic separation equipment, personnel commuting, 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)'. It represents the average production level of titanium concentrate from vanadium-titanium magnetite ore dressing in Sichuan.
Activity Description
This dataset describes the beneficiation of vanadium-titanium magnetite ores in Sichuan. Magnetic separation is the primary technology used in iron ore beneficiation in Sichuan, especially suitable for magnetite and vanadium-titanium magnetite. For non-magnetic or weakly magnetic ores such as hematite, limonite, and siderite, a combination of processes such as roasting, gravity separation, high-intensity magnetic separation, and flotation is generally required to improve the yield and grade of iron concentrate.
The entire iron ore beneficiation production process includes:
Crushing and Grinding: crushing and grinding the ore to liberate iron minerals from gangue.
Magnetic Separation (optional): using low-intensity and high-intensity magnetic separators 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 moisture is removed by filtration to obtain high-grade iron concentrate.
Tailings management: Proper handling of tailings to minimize environmental impact.
Process Description
Titanium concentrate is mined and selected from ilmenite or titanomagnetite, and it is a raw material for producing titanium dioxide, which has a wide range of applications.
