Description
The product represented by this dataset is zinc raw ore, a zinc-rich mineral aggregate obtained after preliminary beneficiation and enrichment following the mining of a zinc mine. The zinc raw ore grade is 4.46%, with zinc mostly occurring in sulfide form; the core zinc-bearing mineral is sphalerite, accompanied by a small amount of oxidized ore. The product mostly appears as lumps or granules with a stable mineral composition, and is the source fundamental raw material of the zinc metallurgy industry chain. Its upstream and downstream industry chains are closely connected: the upstream is the zinc ore primary deposit orebody, obtained from nature through mining operations; downstream, after deep beneficiation processes such as crushing, grinding, and flotation, zinc concentrate is prepared, which is then used to smelt and extract zinc metal, ultimately producing zinc-based alloys, galvanized materials, zinc batteries, chemical zinc compounds, and other products. It is widely used in metallurgy, automotive, electronics, new energy, construction, and other industrial fields, and is a core source mineral product supporting the development of the zinc industry. The entire production process covers the full chain from the initiation of zinc mine mining to the preliminary beneficiation that yields finished zinc raw ore. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants 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 mining, which covers the whole process of obtaining raw zinc ore.
Process Description
Zinc raw ore refers to a zinc-rich mineral aggregate that is mined from a mine and obtained through preliminary beneficiation. The grade of zinc raw ore is 4.46%, and it mostly exists in the sulfide state. The main zinc-containing mineral is sphalerite, and there are also small amounts of oxide minerals such as smithsonite, willemite, hemimorphite, hydrozincite, etc.
