The results show that the ore mineral composition is complex and various minerals are associated. The tungsten minerals are mainly in the form of wolframite output and a small amount in the form of scheelite, and the other elements such as tin, copper, lead, zinc, sulfur, silver are with a low content, so the associated recovery is considered. Due to the complexity of mineral embedded characteristics, uneven dissemination size, different monomer dissociation and complicated property of the gangue minerals containing calcium, floatability close to the tungsten mineral, easy to be over crushed and mud, in accordance with the principle of “recovery and lost as early as possible”, the “gravity-flotation” combined technology will be used as the main process, and the “stage grinding-stage separation” characteristic will be adequately considered for the recovery flowsheet.
