Tungsten ore dressing equipment selection

Tungsten ore dressing equipment selection: Tungsten minerals with industrial value, mainly black tungsten ore and scheelite , their proportions are relatively large, the proportion of wolframite is 7.2 ~ 7.5; the proportion of scheelite is 5.9 ~ 6.1 . Suitable for recycling with re-election. A concentrator tungsten ore, the ore containing mainly wolframite, scheelite also contains, molybdenite, bismuthinite, pyrrhotite, pyrite, arsenopyrite, copper ore and the like. Gangue minerals quartz, followed by the mica, calcite, tourmaline, garnet, apatite and the like. Metal 4.5% to 6.5% of the total mineral.

The test process consists of four parts: (1) hand selection, picking up large pieces of waste rock in the ore; (2) re-election, selecting crude tungsten concentrate from the qualified ore after hand selection; (3) flotation, Recycling other useful minerals from re-selected tailings; (4) Selecting, improving the quality of crude tungsten concentrates and recovering other useful minerals. According to the test procedure, the re-election equipment ore is crushed to 8 mm, -8 to 2 mm, and the jig is selected; 2. 2 mm into the hydraulic classifier (four-chamber hydraulic classifier); 2 to 1 mm, 1 to 0.5 mm , 0.5 to 0.2 mm, 0.2 to 0.07 mm, -0.07 mm. 3, 2 ~ 1 mm and 1 ~ 0.5 mm use jigging; 4, 0.5 ~ 0.2 mm and 0.2 ~ 0.07 mm use shaker; 5, -0.07 mm into the hydraulic classifier; 6, -0.07 ~ 0.04 mm, 0.04 ~ Automatic chute is used for 0.025 mm and 0.025 to 0.013 mm. Jig: double chamber cone diaphragm 1000×1000 mm; Shaker: CC-2 type; Hydraulic classifier: four-chamber trough mechanical discharge type; Automatic chute: five layers 1800×1800 mm.
