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 sinter, a solid block intermediate product prepared from lead-zinc mixed concentrate mixed with flux and return dust through a high-temperature sintering process. Its core component indicators are clear: the zinc content is 41.76%, the total lead and zinc content (Pb+Zn) is greater than 48%, the sulfur (S) content is approximately 5.5~6.5%, and the lead-to-zinc ratio is approximately 1:2.2; the product has the physical characteristics of a dense structure and relatively high hardness, which can effectively reduce losses during transport and is compatible with the requirements of subsequent smelting processes. The upstream and downstream industry chains of this product are closely connected: the upstream core raw material is lead-zinc mixed concentrate, and downstream it is directly applied to the lead-zinc smelting stage, serving as the core raw material for subsequent processes such as reduction smelting and converting, used for efficiently extracting lead and zinc metals, thereby producing lead-zinc alloys, lead-acid batteries, zinc-based functional materials and other products, broadly supporting the development of metallurgy, electronics, new energy, chemical industry and other industrial fields. The entire production process focuses on the sintering stage, covering the entire conversion process from the batching of lead-zinc mixed concentrate to the output of the sinter 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 sintering process, covering the entire process from lead-zinc mixed concentrate to sintered blocks.
Process Description
Sinter block is a solid block product formed by high-temperature sintering process from lead-zinc mixed concentrate with flux and returned smoke dust. The zinc content is 41.76%, the Pb+Zn content is greater than 48%, the S content is about 5.5~6.5%, and the lead-zinc ratio is about 1:2.2. It has a dense structure and high hardness, which is convenient for transportation and subsequent smelting.
