Description
This dataset represents the processing of magnetite ore through mineral beneficiation in Hebei, covering the entire life cycle inventory (cradle-to-gate) from crushing to the production of hematite concentrate. It includes all activities related to 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 by integrating data from multiple 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 represents the average production level of magnetite beneficiation in Hebei.
Activity Description
This dataset describes the beneficiation of magnetite ore in Hebei. Magnetic separation is the primary technology used in iron ore beneficiation in China, especially suitable for magnetite and vanadium-titanium magnetite. For non-magnetic or weakly magnetic ores such as hematite, limonite, and siderite, a combination of techniques 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-intensity 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 conducted 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
The iron concentrate grade in this dataset is 66.25%, which is the primary product of the mineral beneficiation process. The main component of the iron concentrate is magnetite (Fe₃O₄). Due to the good magnetic properties of magnetite, the contents of impurities such as silicon, phosphorus, and sulfur in the ore are low, with strict impurity control, making it suitable for iron and steel smelting.
