A mineral processing test was conducted to treat a lithium-tantalum-niobium-beryllium polymetallic ore with a lithium grade of 0.68％from Xinjiang.According to the process mineralogy study,this ore has spodumene as the dominant lithium minerals,and has low content of tantalum-niobium minerals.A flowsheet including a magnetic separation and gravity separation to recover tantalum-niobium minerals,and a flotation to collect lithium minerals can produce a tantalum-niobium concentrate with Ta2O5 grade and recovery of 17.110％and 41.69％,Nb2O5 grade and recovery of 19.670％and 42.63％,respectively,and a lithium concentrate with Li2O grade and recovery of 5.12％and 75.21％,respectively.
