The product represented by this dataset is copper-nickel mixed concentrate, a core intermediate mineral product obtained from nickel ore through the full mining and beneficiation process of crushing, grinding, flotation, and dewatering. Its core characteristics are prominent: it appears as a powdery or granular solid with high metal content and low impurity content, in which the nickel content reaches 8.6%, far higher than the mine's average grade of 0.96%, indicating an outstanding enrichment effect. Its main chemical components are nickel and copper, with associated elements such as iron and sulfur, and its compositional characteristics are highly compatible with subsequent smelting processes. Its upstream and downstream industry chains are closely connected: the upstream core raw material is the nickel ore primary orebody, and downstream it is directly applied in the electrolytic nickel smelting industry as the core raw material for extracting electrolytic nickel. After smelting and processing, it can yield metal products such as electrolytic nickel and electrolytic copper, broadly supporting the development of metallurgy, new energy, electronics, aerospace, and other industrial fields, and it is a key source intermediate product in the nickel-copper industry supply chain. The entire production process covers the full chain from the initiation of nickel ore mining and beneficiation to the output of finished copper-nickel mixed concentrate. 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.
