Description
This dataset represents the life cycle inventory (cradle-to-gate) of magnetite ore processing through beneficiation in Shandong, covering all activities related to the production of hematite concentrate. It excludes greenhouse gas emissions, both direct and indirect, from the production of crushing equipment, magnetic separation equipment, employee 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)', and is representative of the average production level of magnetite beneficiation in Shandong.
Activity Description
This dataset describes the beneficiation of magnetite ore in Shandong. 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 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: breaking and 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 carried out through flotation or gravity separation processes.
Screening and filtration (optional): Screen to control mineral particle size and filter to remove moisture, producing high-grade iron concentrate.
Tailings management: Properly manage tailings to minimize environmental impacts.
Process Description
The iron concentrate in this dataset has a grade of 64.29% and is the primary product of the mineral processing stage. The main component of the iron concentrate is magnetite (Fe₃O₄). Due to its favorable magnetic properties, the magnetite ore contains low levels of impurities such as silicon, phosphorus, and sulfur, with strict impurity control, making it suitable for iron and steel smelting.
