Study of recovering sulfide ore from tungsten gravity tailings in Jiangxi

A tungsten polymetallic ore in Jiangxi contains mainly the wolframite,which Main valuable elements are WO₃,Sn,Mo and Cu. After recovering tungsten ores by gravity concentration technology,the tailings contain large amounts of chalcopyrite and molybdenite. According to the characteristic and nature of the tailings,the research adopts the process of Cu-Mo bulk flotation and Cu-Mo separation floating,obtains good metallurgical performance. As a result,the copper concentrate contains Cu 23.13 % with recovery of 95.21 %; the Molybdenum concentrate contains Mo 43.49 % with recovery of 81.93 %;
