锑金精矿富氧强化挥发技术数据集

本数据集围绕锑金精矿富氧强化挥发技术，通过热力学与动力学分析优化工艺参数，系统探究并实现锑的高效回收。在1000~1300 ℃范围内Sb-S-O体系的热力学计算结果有效指导了挥发工艺优化。单因素实验确定最佳条件为：焙烧温度1250 ℃、时间90 min、氧气浓度30%、通气速率1.2 L/min、升温速率10 ℃/min、物料粒度63–88 μm，在最佳工艺条件处理含Sb 34.53%、含S 34.7%的锑金精矿，Sb和S的整体回收率可以达到99.3%和99.08%。XRD、SEM/EDS和XPS分析证实，挥发后渣中Sb2O3相消失，烟尘中富集Sb2O3，渣相以Sb2O3为主，锑硫挥发充分。热分析与动力学模拟（Flynn-Wall-Ozawa、Kissinger和Coats-Redfern法）揭示了锑的相变规律及挥发机制。该研究建立了锑金精矿多组元定向分离调控机制，为富氧熔池熔炼提供了高回收率（锑挥发率>98%）的理论支撑和工艺优化依据，对工业应用具有重要指导价值。本数据集主要包括锑金精矿及实验产物的物化表征数据、Sb-Fe-O系热力学信息，锑挥发控制参数的探究数据、挥发动力学模拟计算，数据集大小为92.9MB。This dataset centers on the oxygen-enriched intensified volatilization technology for antimony-gold concentrate. It optimizes process parameters via thermodynamic and kinetic analyses, systematically investigates and achieves efficient antimony recovery. Thermodynamic calculations of the Sb-S-O system within the temperature range of 1000–1300 ℃ effectively guided the optimization of the volatilization process. Single-factor experiments determined the optimal conditions as follows: roasting temperature of 1250 ℃, holding time of 90 min, oxygen concentration of 30%, aeration rate of 1.2 L/min, heating rate of 10 ℃/min, and particle size of 63–88 μm. When treating antimony-gold concentrate with 34.53% Sb and 34.7% S under these optimal conditions, the overall recovery rates of Sb and S reached 99.3% and 99.08%, respectively. Analyses via XRD, SEM/EDS and XPS confirmed that after volatilization, the Sb₂O₃ phase in the slag disappeared, Sb₂O₃ was enriched in the flue dust, the slag phase was mainly composed of Sb₂O₃, and antimony and sulfur were sufficiently volatilized. Thermal analysis and kinetic simulations using the Flynn-Wall-Ozawa, Kissinger and Coats-Redfern methods revealed the phase transition rules and volatilization mechanism of antimony. This study established the directional separation and regulation mechanism of multi-components in antimony-gold concentrate, providing theoretical support and process optimization basis for oxygen-enriched bath smelting with high recovery rate (antimony volatilization rate > 98%), which has important guiding significance for industrial applications. This dataset mainly includes physicochemical characterization data of antimony-gold concentrate and experimental products, thermodynamic information of the Sb-Fe-O system, investigation data of antimony volatilization control parameters, and volatilization kinetic simulation calculations, with a total size of 92.9 MB.
