摘　　要：辽宁义县萤石矿萤石与石英、碳酸盐和硫化物关系密切,浸染粒度细,是较难开发利用和提升产品品级的主要原因。通过岩矿鉴定和XRD分析,确定了矿石性质,酸性水玻璃、硫酸铝、木质素磺酸钙为复合抑制剂,通过阶段磨矿-3次除杂-2次粗选-5次精选-2次扫选-中矿集中处理的工艺流程,最终萤石精矿质量达到Ca F2 98.28%,Ca CO3 0.83%,Si O2 0.54%,S 0.07%,符合酸级萤石质量标准。Fluorite of fluorite mine in Liaoning Yi county is closely related to quartz, carbonates and sulfides, the dissemination size is fine, which is the main difficulty for the development and utilization and upgrading product grade. We determine the ore property by mineral examination and XRD analysis, using acidic water glass（AWG）, aluminum sulfate, calcium lignosulfonate as the complex depressant, through stage grinding - three purification - two roughings - five cleanings - two scavengings - middles centralized processing, the final fluorite concentrate containing CaF： 98.28%, CaCO3 0.83%, SiO2 0.54%, S 0.07%, the acid level is in line with the quality standard.
