Embodiment 1
[0023] A combined calcium-containing gangue depressant for scheelite flotation. The components are sodium lignosulfonate, humic acid and carboxylated chitosan, and the contents are respectively 40%, 50% and 10%.
[0024] A preparation method of the calcium-containing gangue combined inhibitor for scheelite flotation, comprising: 40% sodium lignosulfonate, 50% humic acid, 10% carboxylated chitosan %, mixed to prepare the calcium-containing gangue combined inhibitor DWC for scheelite flotation, then heated to 80°C, added water until the mass concentration of the inhibitor DWC was 20%, and stirred at a high speed of 1000r / min After 10 minutes, an aqueous solution of the inhibitor DWC was prepared, which was further diluted to a 2% solution for later use.
[0025] A method for flotation scheelite using the above combined inhibitor, comprising:
[0026] (1) Grind the scheelite through a ball mill to -74 microns and account for 70%; the adopted scheelite contains tungsten (WO 3 ) ...
Embodiment 2
[0034] A combined calcium-containing gangue depressant for scheelite flotation. The components are sodium lignosulfonate, sodium humate and carboxylated chitosan, and the contents are respectively 40%, 55% and 5%. A preparation method of the calcium-containing gangue combined inhibitor for scheelite flotation, comprising: 40% sodium lignosulfonate, 55% sodium humate, carboxylated chitosan 5%, mixed to prepare the calcium-containing gangue combined inhibitor DWC for scheelite flotation, then heated to 80°C, added water until the mass concentration of the inhibitor DWC was 30%, at a high speed of 1500r / min Stir for 15 minutes to prepare an aqueous solution of the inhibitor DWC, which is further diluted to a 2% solution for later use.
[0035] A method for flotation scheelite using the above combined inhibitor, comprising:
[0036] (1) Grind the scheelite through a ball mill to -74 microns and account for 75%; the adopted scheelite contains tungsten (WO 3 ) is about 0.54%, CaO ...
Embodiment 3
[0044] A combined calcium-containing gangue depressant for scheelite flotation. The components are sodium lignosulfonate, sodium humate, and carboxylated chitosan, and the contents are respectively 35%, 60%, and 5%.
[0045] A preparation method of the calcium-containing gangue combined inhibitor for scheelite flotation, comprising: 35% sodium lignosulfonate, 60% sodium humate, carboxylated chitosan 5%, mixed to prepare the calcium-containing gangue combined inhibitor DWC for scheelite flotation, then heated to 80°C, added water until the mass concentration of the inhibitor DWC was 25%, at a high speed of 1200r / min Stir for 10 min to prepare an aqueous solution of the inhibitor DWC, which is further diluted to a 2% solution for later use.
[0046] A method for flotation scheelite using the above combined inhibitor, comprising:
[0047] (1) Grind the scheelite through a ball mill to -74 microns and account for 75%; the adopted scheelite contains tungsten (WO 3 ) is about 0.36%,...
