Description
This dataset represents a product that is tin oxide, a high-purity inorganic oxide product prepared from tin concentrate with a grade of 40.05% via a roasting process, with a tin oxide content of up to 99.85%. Its appearance is a white, light-yellow or light-grey tetragonal, hexagonal or orthorhombic crystalline powder, with a density of 6.95 g/mL at room temperature, a melting point of 1630℃ and a boiling point of 1800℃; it has stable physicochemical properties and is also a transparent conductive material with excellent performance. The upstream raw material of this product is tin concentrate, and the downstream is widely applied in the preparation of transparent conductive films, electronic-component production, ceramic-glaze processing, catalyst synthesis and tin-based functional material preparation; it is an important deep-processing oxide product in the tin metallurgy industrial chain. 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.

Technology comment
The tin concentrate roasting process mainly includes the following steps: crush and screen the tin concentrate to a suitable particle size, then contact it with air or oxygen-rich gas, and heat it in a high-temperature roasting furnace to oxidize and volatilize the sulfide and some impurities (such as arsenic and antimony) in the tin ore to generate tin oxide.
