Description
The product represented by this dataset is lead-silver concentrate, which is the core product after the beneficiation and enrichment of lead-silver oxidized ore. Its core grade indicators are 60% lead and 1195.19 g/t silver, with an approved beneficiation process yield of 6.24% and valuable-element recovery indicators of 90% lead recovery and 88% silver recovery. Its upstream feedstock is lead-silver oxidized ore raw ore, and downstream it serves as the core raw material for pyrometallurgical/hydrometallurgical lead-silver smelting, achieving the extraction and purification of the valuable metals lead and silver through the smelting process. This concentrate enriches the core valuable lead and silver components of the raw ore and is a key intermediate product of the lead-silver metallurgy industry chain. 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 beneficiation process. The ore beneficiation adopts a flotation process comprising one stage of roughing, two stages of scavenging, and two stages of cleaning, with sodium carbonate as the slurry pH adjuster. This involves four processes: crushing and screening, grinding and classification, flotation, and concentration and dewatering. The entire process covers the steps from raw ore to silver-lead concentrate.
