| General comment on data set | Nickel ore is mined from a typical nickel-copper sulfide deposit in Gansu, China (~0.96% Ni). After crushing, flotation, and dewatering, a mixed nickel-copper concentrate (~8.6% Ni) is obtained. The relevant data is sourced from on-site production data from the Gansu nickel-copper sulfide mine. Using pyrometallurgical smelting—flash smelting technology—the nickel is concentrated into high nickel matte. The relevant data is from the operational data published by Jinchuan Group Co., Ltd. in China. Through grinding, flotation, and the electrolysis method (GFEM), high-purity nickel metal (>99.96%) is deposited in nickel sulfide electrolysis cells. The relevant data is also from the operational data published by Jinchuan Group Co., Ltd. Nickel sulfate is prepared by sulfuric acid acidification, with relevant data sourced from large-scale plant data in Germany used in Ecoinvent. Waste treatment data is sourced from the reference (Bai et al., 2022). |
