Description
Sulfur concentrate is a by-product extracted from tin raw ore through crushing, grinding, gravity separation and other processes, with a sulfur content of no less than 38%, mainly composed of sulfur, iron and trace elements such as lead and zinc. The upstream raw material of this product is tin raw ore; downstream, it serves as an important chemical raw material, with its core use being processing into sulfuric acid, widely applied in phosphate fertiliser production, metal pickling and pharmaceutical fields. With technological progress, from 2024 sulfur concentrate began to be used as a key material for sulfide all-solid-state batteries, expanding new energy application scenarios. The dataset contains the main raw and auxiliary materials, energy and waste of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.

Process Description
Sulfur concentrate is a by-product obtained from tin ore through crushing, grinding, gravity separation, and other beneficiation processes. It contains at least 38% sulfur and consists mainly of sulfur- and iron-bearing minerals with small amounts of lead, zinc, and other constituents. Sulfur concentrate is an important chemical raw material used mainly to produce sulfuric acid, whose downstream applications include phosphate-fertilizer production, metal pickling, and other chemical processes. Flotation, gravity separation, and other beneficiation methods may be used in its production.

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.
