Description
This dataset is a market activity dataset, representing a combination of provincial "limonite ore" markets within the North China region of China, i.e., the "limonite ore" market group for the North China region. Transportation losses, transportation modes, and infrastructure are not included in this dataset; they are covered in the respective provincial market datasets. The North China region of China includes: Beijing, Tianjin, Hebei, Shanxi, and Inner Mongolia. Data sources include the China Transportation Yearbook, China Energy Statistics Yearbook, China Statistical Yearbook, and customs statistics from the General Administration of Customs.
Activity Description
This dataset is a market activity dataset. Each market represents a consumption mix of products within a specific region, connecting suppliers with consumers of the same product within that region. Markets encompass both producers and importers of the product within the same geographical area. Additionally, markets account for the transportation of products to consumers, as well as losses occurring during the transport process.
Process Description
Limonite, primarily composed of hydrated iron oxides (FeO(OH)·nH2O), includes goethite, lepidocrocite, akaganeite, feroxyhyte, and hydrohematite. Limonite is rich in crystalline water, with a specific magnetic susceptibility of (20–80) × 10⁻⁶ m³/kg, a density of (3.0–4.2) g/cm³, and a Mohs hardness ranging from 1.0 to 5.5. During crushing and grinding processes, limonite is prone to sludging, which not only increases grinding energy consumption and reagent dosage but also reduces beneficiation efficiency, leading to resource waste.
