Description
This dataset represents a product that is refined tin, a high-purity tin-metal product obtained after refining treatment of crude tin, with high tin content and low impurity content, a silvery-white metallic lustre, excellent electrical conductivity, ductility and corrosion resistance, and stable physicochemical properties. The upstream raw material of this product is crude tin, and the downstream is widely applied in metallurgical casting, electronic-component manufacturing, chemical anti-corrosion coatings, tin-based alloy preparation and other industrial fields; it is an indispensable important non-ferrous metal raw material in national economic development. The dataset includes the main raw and auxiliary materials, energy and wastes in the production process; infrastructure such as the manufacture of production equipment and plant construction is not included within the boundary of the dataset; the data inventory is formed by merging data from multiple sources.
Activity Description
The crude tin is melted and then charged into a refining furnace, where the molten tin is maintained at an appropriate temperature by heating. During the refining process, impurities are removed by adding fluxes or by methods such as blowing and molten stirring. Subsequently, the molten tin undergoes clarification, settling, and filtration to ensure its purity meets industrial requirements, ultimately producing refined tin with high tin content and low impurity levels.
Process Description
Refined tin is a tin metal product that has undergone roasting, reduction smelting, and refining. It has high tin content and low impurity content, exhibits good conductivity, ductility, and corrosion resistance, and typically has a silvery-white metallic luster. It can be used in industrial applications such as metallurgy, electronics, the chemical industry, and alloy manufacturing.

After the crude tin is melted, it is added to the refining furnace and the tin liquid is kept at a suitable temperature by heating. During the refining process, impurities are removed by adding additives or blowing, melting and stirring. Subsequently, the tin liquid undergoes clarification, precipitation and filtration to ensure that its purity meets industrial requirements, and ultimately refined tin with high tin content and low impurity content is obtained.
