Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is tin concentrate, a tin-rich mineral product obtained from tin raw ore through beneficiation processes such as crushing, grinding and gravity separation for enrichment and purification, with a tin content of 45%, and impurity components mainly being elements such as iron, silicon, tungsten and copper; its appearance is mostly dark brown to grey-black in sandy granular or powder form, possessing the physical characteristics of high specific gravity and hard texture, with stable chemical properties, not easily oxidized or dissolved at room temperature, and both its electrical conductivity and magnetism are relatively weak, being the core raw material suitable for the smelting method to extract metallic tin. The upstream raw material of the product is tin raw ore; downstream it serves as the core feed for the tin smelting process, through which metallic tin and tin-based alloys can be prepared, being a key intermediate mineral product connecting the preceding and following stages in the tin metallurgy industry chain. The dataset includes the main raw and auxiliary materials, energy and waste of the production process; infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The tin beneficiation process includes crushing, ball milling, fine screening, flotation, shaking table primary separation, shaking table scavenging, and shaking table cleaning. The entire process covers from tin raw ore to tin concentrate.
Process Description
Tin concentrate is a tin-rich mineral product extracted from tin raw ore through processes such as crushing, grinding, and gravity separation. Its tin content is approximately 45%, with impurities mainly consisting of iron, silicon, tungsten, copper, and other elements. It typically appears as a dark brown to gray-black sandy or powdery material with a high specific gravity, stable chemical properties, and resistance to oxidation or dissolution at room temperature. Tin concentrate is hard in texture, has weak electrical conductivity and magnetism, and is suitable for extracting metallic tin through smelting.

Technology comment
The tin beneficiation process flow includes crushing, ball milling, fine screening, flotation, shaking table roughing, scavenging, and cleaning. First, the raw ore is crushed through crushing and ball milling to achieve dissociation of useful mineral monomers, and then finely screened and classified to ensure qualified particle size. Then, flotation is used to preferentially remove easily floatable sulfides and other impurities, creating favorable conditions for subsequent gravity separation. The flotation product enters the gravity separation stage with shaking tables as the core. Through roughing, a large amount of tailings is discarded and a coarse concentrate is obtained. Scavenging recovers residual fine tin to improve the overall recovery rate. Finally, the coarse concentrate is purified through cleaning, resulting in a high-grade qualified tin concentrate.
