摘　　要：为资源化综合利用锂辉石冶炼渣,开展了锂渣工艺矿物学研究。结果表明:锂冶炼渣中主要矿物有锂辉石、硅铝酸(HAlSi_(2)O_(6))、玻璃体(硅铝酸盐)、石英、石膏、长石及少量铁矿物和钽铌矿物;锂冶炼渣中的铁主要赋存于硅铝酸、玻璃体以及角闪石中,硫主要以硫酸钙形式存在,其硫占总硫的99.54%;渣中可见伴生钽铌矿物以细晶石、钽铌铁矿单体颗粒存在,或与硅铝酸、正长石、石英等连生,Ta_(2)O_(5)含量为134 g/t、Nb_(2)O_(5)含量为143 g/t。In order to comprehensively utilize lithium smelting slag,the process mineralogy of lithium was studied.The results indicated that the main minerals of lithium smelting slag contained spodumene,silicoaluminate(HAlSi_(2)O_(6)),glass body(aluminum silicates),quartz,gypsum,feldspar and a small amount of iron minerals and tantalum-niobium minerals.Iron in lithium smelting slag mainly occurs in silicoaluminate,glass body and hornblende.Sulfur mainly exists in the form of calcium sulfate,which is accounting for 99.54% of total sulfur.The associated tantalum-niobium minerals exist as fine crystal and tantalum-niobium iron ore monomer particles,or intergrowth with silicoaluminate,orthoclase,quartz,etc,and the grade of Ta_(2)O_(5) and Nb_(2)O_(5) in lithium smelting slag is 134 g/t and 143 g/t respectively.
