Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is cathode zinc, a core intermediate product produced in the electrowinning process of the hydrometallurgical zinc smelting flow, with significant core characteristics: the zinc purity can reach 99.99%, with extremely low impurity content and strong purity stability; it appears mostly in sheet or plate form, with a regular physical form and stable chemical properties, and can directly match the requirements of subsequent melting and casting. Its upstream and downstream industry chains are closely connected: the upstream core raw material is purified zinc sulfate solution (obtained from the leaching, purification and refining of zinc calcine), and downstream is the metallic zinc melting and casting stage, serving as the core raw material for the melting and casting process. After heating, melting, refining and impurity removal, and casting, finished metallic zinc is prepared, which is then processed into terminal products such as galvanized materials and zinc alloys, widely supporting the development of construction, transportation, power, manufacturing and other industrial fields, being the key intermediate carrier connecting purified zinc sulfate solution and finished metallic zinc in the hydrometallurgical zinc smelting industry chain. The entire production process focuses on the electrowinning stage of hydrometallurgical zinc smelting, with the full process covering the entire electrochemical conversion process from the input of purified zinc sulfate solution to the output of finished cathode zinc. The dataset includes the main raw and auxiliary materials, energy and waste of the production process; infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the electrowinning process of zinc hydrometallurgy, covering the entire process from new zinc sulfate solution to cathode zinc.
Process Description
The cathode zinc obtained by the electrowinning process is an important intermediate product of hydrometallurgical zinc smelting. The zinc purity can reach 99.99% and is suitable for subsequent melting and casting of metallic zinc.

Technology comment
The purified zinc sulfate solution is added with additives (bone glue, strontium carbonate, etc.), and is continuously sent to the electrolytic cell through a high-level tank for electrolytic deposition to obtain cathode zinc (Zn99.99%). The metal recovery rate during the electrolysis process is 99.30%.
