Description
This dataset represents the full life cycle inventory (cradle-to-gate) of iron ore processing via mineral beneficiation in Inner Mongolia, covering all activities related to the production of hematite concentrate. However, it does not include direct or indirect greenhouse gas emissions from the production of crushing equipment, magnetic separation equipment, employee commuting, or daily office operations during the beneficiation process. The dataset was formed by integrating data from multiple sources based on Chinese 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 iron ore beneficiation in Inner Mongolia.
Activity Description
This dataset describes iron ore beneficiation in Inner Mongolia. 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 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 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 water is removed by filtration to obtain high-grade iron concentrate.
Tailings management: Proper handling of tailings to minimize environmental impacts.
Process Description
In this dataset, the iron ore concentrate has a grade of 65.47%, belongs to transition metals, and is the primary product of the mineral processing stage. Iron concentrate is typically in powder form and is widely used in downstream processing operations at sintering and pelletizing plants, serving as a key raw material for 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.
