Filtrating solution before ion exchange in Tungsten hydrometallurgy by ceramic membrane separation technology was studied .The results show that the solution turbidity can reach 0 .53 NTU after filtrating which is superior to 4 .36 NTU by the traditional technology of plate‐frame pressure filtration and fine filtration .The operating conditions ,concentration multiple and the membrane types were examined by single factor test .The results show that the suitable operating parameters are ceramic membranes of 200 × 37 × 1016 ,membrane surface velocity of 4 m/s ,backwash cycle of 15 minutes ,transmembrane pressure of 0 .20 M Pa ,and concentration multiple of 40 times .Under the suitable results ,the ceramic membrane is long‐term stabilization and reusable .
