Included activities ends

The activity concludes with the delivery of \"Limonite\" to consumers of the product within the East China region.

Description

This dataset is a market activity dataset, combining the provincial markets of Limonite ore in the East China region, thus forming the East China regional Limonite ore market group. Transport losses, means of transport, and transport infrastructure are not included in this dataset; they are instead included in the respective provincial market datasets. The East China region includes: Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, and Shandong. Data sources include the Year Book of China Transportation & Communications, China Energy Statistics Yearbook, China Statistical Yearbook, and the General Administration of Customs statistics data, among others.

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.
