Description
This dataset represents a product that is refined zinc, a high-purity zinc product prepared by refining or electrolytic-distillation processes of crude zinc, with distinctive core characteristics: a zinc content of up to 99.995% and extremely low impurity content, giving an outstanding purity advantage; it appears as metallic blocks or ingots, has good ductility and electrical conductivity, and can be directly adapted to various end-use industrial scenarios. Its upstream and downstream industrial chain is closely linked: the upstream core raw material is crude zinc, and the distillation process requires supporting auxiliary materials such as heat-transfer media and purifying auxiliaries; the downstream application fields are extensive, being directly used in metallurgical processing, chemical-product synthesis, alloy manufacturing and galvanizing protection and other industrial scenarios, supporting the development of automotive, electronics, new energy, construction, shipbuilding and other key industrial fields; it is one of the core end products of the lead–zinc smelting industrial chain. The entire production process focuses on the distillation stage, with the full process covering the entire high-purity transformation process from the input of crude zinc to the output of the refined-zinc product. 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 entire production process includes the distillation process, covering the entire process from crude zinc to refined zinc.
Process Description
Refined zinc is a high-purity zinc product obtained by refining or electrolytic distillation of crude zinc. The zinc content is 99.995% and the impurity content is extremely low. It is in the form of metal lumps or ingots. It has good ductility and conductivity and can be directly used for industrial purposes such as metallurgy, chemical industry, alloy manufacturing, and galvanizing.

Technology comment
The crude zinc is then sent to a distillation tower or electrolytic cell for refining. By controlling the temperature and pressure, impurities are separated through evaporation or deposition based on the boiling point difference between zinc and impurity elements, thereby further purifying the zinc and ultimately obtaining high-purity refined zinc.
