摘　　要：雅江县锂多金属矿中Li_(2)O品位为1.49%,其中的铌、钽、锡等元素也达到综合利用标准。研究中采用化学多元素分析、光学显微分析、X射线衍射分析、人工重砂、电子探针、扫描电镜-能谱检测等多种分析手段,对锂多金属矿进行工艺矿物学研究。查明了原矿的矿物组成和化学性质,主要矿物的嵌布粒度、赋存状态、共生关系。在此基础上指出了影响此矿石中锂辉石、铌钽铁矿、锡石回收的因素,并对后续的选冶试验工作提出建议。Li-poly-metallic ore occurs in Yajiang county,Sichuan Province.This paper deals with process mineralogy of the ore and technology of multi-element chemical analysis,optical microscopy,X-ray diffraction analysis,artificial panning,electronic probe,scanning electronic microscope-energy spectrum detection etc.are applied to study the process mineralogy.Li_(2O) grade of the ore is 1.49% and niobium,tantalum and tin can be recovered as by-products.Mineral composition,chemical property of the raw ore,embed partial size of the main minerals and occurrences and their symbiotic relationship are acertained.Then factors affecting recovery of spodumene,niobium tantalite and cassiterite of the ore are pointed out and suggestion proposed for later ore dressing and metallurgical experiments.
