Description
The product represented by this dataset is lead-silver oxidized ore raw ore, with raw-ore grades of 4.16% lead and 84.75 g/t silver. The valuable useful components in the ore are the two core elements lead (Pb) and silver (Ag). The lead-bearing minerals in the ore are mainly galena, followed by cerussite, with a small amount of associated minor lead-bearing manganese oxide and mimetite; the silver-bearing minerals are mainly argentite, followed by silver-bearing tetrahedrite, stromeyerite, and freibergite, together with small amounts of other metallic minerals such as pyrite and magnetite. The non-metallic minerals are mainly dolomite, quartz, muscovite, sericite, and a small amount of graphite. The metallic minerals are mostly galena, distributed in an uneven disseminated form, and no gold minerals are observed in the ore. This raw ore is the core raw material for lead-silver smelting and processing, with no upstream processed materials. Downstream, it can serve as feed for beneficiation and smelting processes, achieving the resource utilization of the valuable metals lead and silver through beneficiation enrichment and smelting extraction. 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 the raw ore mining process.
Process Description
The ore is lead–silver oxide ore, with head grades of 4.16% Pb and 84.75 g/t Ag. The mining recovery rate is 85%, and the mining dilution rate is 10%. The lead-bearing minerals are mainly galena, followed by cerussite, with minor lead-bearing manganese oxide and mimetite. The silver-bearing minerals are mainly argentite, followed by silver-bearing tetrahedrite, stromeyerite, and freibergite. Other metallic minerals include minor pyrite and magnetite. The non-metallic minerals are mainly dolomite, quartz, muscovite, sericite, and minor graphite. The metallic minerals are dominated by galena, with minor cerussite, pyrite, and magnetite, and occur as uneven disseminations; no gold minerals were observed. The valuable components of the ore are Pb and Ag.
