Description
The product represented by this dataset is copper concentrate, a by-product extracted from tin raw ore through processes such as crushing, grinding, and gravity separation. It has a copper content of not less than 16% and is suitable for the extraction of copper metal by the smelting method. The upstream feedstock of this product is tin raw ore, and downstream it serves as the core feed for the copper smelting process. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants is not included within the dataset boundary. The data inventory is formed by merging data from multiple sources.

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.
