Description
This dataset is a market activity dataset, representing a combination of provincial "hematite ore" markets within the Central China region, i.e., the "hematite ore" market group for Central China. Transportation losses, transport vehicles, and transportation infrastructure are not included in this dataset; they are covered in the respective provincial market datasets. Central China region includes: Henan, Hunan, and Hubei. Data references include the "China Communications Yearbook", "China Energy Statistical 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
Iron ore is the main raw material for steel production, and steel is one of the core materials for modern industry and infrastructure. Hematite, with the chemical composition α-Fe2O3, is an oxide mineral belonging to the hexagonal crystal system and exhibits polymorphism with maghemite (γ-Fe2O3), which crystallizes in the isometric system. It has a Mohs hardness of 5.5–6.5. In China's iron ore resources, hematite accounts for a significant proportion and is characterized by wide distribution, large reserves, and low grade. Compared to magnetite, hematite has finer mineral grain size, higher clay content, and greater beneficiation difficulty.
