Study on mineral processing technology of scheelite in north-east China

A tungsten ore in north-east China is skarns scheelite primary deposit.In a scheelite flotation,Na_2CO_3 is used as a regulator,Na_2SiO_3 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% WO_3,a scheelite concentrate containing 75.01% WO_3 can be obtained with the recovery of 91.89%.
