Description
This dataset represents the life cycle inventory (cradle-to-gate) of iron ore processed through beneficiation in Shanxi, covering all activities related to iron concentrate beneficiation production from the beginning of crushing to the production of hematite concentrate, but excluding 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 is formed by merging 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)', representing the average production level of iron ore beneficiation in Shanxi.
Activity Description
This dataset describes iron ore beneficiation in Shanxi Province. Magnetic separation is the primary technology used in Hunan's iron ore beneficiation, 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 iron ore beneficiation process includes: crushing and grinding—breaking 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 conducted 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 impact.
Process Description
The iron concentrate in this dataset has a grade of 65.88%, belongs to transition metals, and is the primary product of the mineral beneficiation process. Iron concentrate is typically in powder form and is widely used in downstream processing technologies such as sintering plants and pelletizing plants, serving as a key raw material in steel production.

Technology comment
This dataset describes the beneficiation of iron ore. The beneficiation process aims to separate valuable iron minerals from iron ore, remove impurity minerals, thereby increasing the grade, and providing high-quality raw materials for subsequent smelting processes.
