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 crude zinc, a metal intermediate product obtained by smelting lead-zinc sinter. Its core component is zinc, with a zinc content of 98%, accompanied by a small amount of impurities such as lead, iron, and copper. The product appears as a metal block or ingot, with metallic luster and a regular physical form, facilitating subsequent processing. Its upstream and downstream industry chains are closely connected: the upstream core raw material is lead-zinc sinter; downstream it is mainly applied to the zinc refining stage, where high-purity zinc can be prepared through electrolytic refining or pyrometallurgical refining processes, further used to produce zinc-based alloys, galvanized materials, zinc batteries, chemical zinc compounds and other products, broadly supporting the development of metallurgy, automotive, electronics, new energy, chemical industry and other industrial fields. The entire production process focuses on the smelting stage, covering the entire conversion process from the input of lead-zinc sinter to the output of the crude zinc product. The dataset includes the main raw and auxiliary materials, energy and waste of the production process, while 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 smelting process, covering the entire process from sintered blocks to crude zinc.
Process Description
Crude zinc is a product obtained by smelting lead-zinc sintered blocks. The main component is zinc, with a zinc content of 98%. It may also contain a small amount of lead, iron, copper and other impurities. It is in the form of metal lumps or ingots and is suitable for further refining or electrolysis to prepare high-purity zinc.

Technology comment
When the sinter block undergoes reduction smelting in the blast furnace, zinc oxide is reduced, the zinc volatilizes as vapor, and is introduced into a condenser to condense into crude zinc. Lead oxide is reduced to metallic lead, which flows downward through the charge in a liquid state and is discharged from the hearth together with the slag. The mixture is then separated by settling in the forehearth, yielding crude lead and slag.
