Description

This dataset is a compilation of market activity datasets specifically for Limonite ore markets across the provincial level in the Northwestern region of China, i.e., the aggregated Limonite ore market of the Northwestern region. Transportation losses, methods of transportation, and transport infrastructure are not included in this dataset; they are included in the respective provincial market datasets. The Northwestern region of China includes: Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. Data reference sources include the Year Book of China Transportation & Communications, the China Energy Statistics Yearbook, the China Statistical Yearbook, and the General Administration of Customs statistical data, etc.

Activity Description

This dataset is a market activity dataset, where each market represents a consumption mix of products within a specific region, connecting suppliers with consumers of the same product within that region. The market covers producers and importers of the product within the same geographical area. In addition, the market also takes into account the transport, freight of the product to the consumer, and losses during transportation.

Process Description

Limonite ore, whose main component is hydrated iron oxide (FeO(OH)·nH2O). Limonite ore includes goethite, lepidocrocite, ferrihydrite, hydrous ferrihydrite, and hydrous hematite, among others. Limonite is rich in crystallization water, with a specific magnetic susceptibility of (20～80)×10^-6 m^3/kg, a density of (3.0～4.2) g/cm^3, and a Mohs hardness of 1.0～5.5. During crushing and grinding, it is relatively prone to form slimes, which not only increases the energy consumption of grinding and dosage of reagents but also lowers the beneficiation indexes, leading to resource wastage.
