摘　　要：东北某钨矿为矽卡岩型白钨原生矿床,用Na2CO3作pH调整剂,用Na2SiO3和YN作脉石抑制剂,ZL作捕收剂,经过加温精选,当原矿品位(WO3)为2.83%时,可获得品位(WO3)75.01%的一级Ι类白钨精矿,WO3回收率91.89%.A tungsten ore in north-east China is skarns scheelite primary deposit. In a scheelite flotation, Na2CO3 is used as a regulator, Na2SiO3 and YZ are used as gangue depressants, and ZL as a collector. The scheelite rougher concentrate is cleaned at 90-95℃. When the raw ore contains 2.83% WO3, a scheelite concentrate containing 75.01% WO3 can be obtained with the recovery of 91.89%.
