Examples
Embodiment 1
[0016] Test conditions: 500g andesite porphyrite molybdenite, grade 0.6%, grinding fineness -400 mesh 80%. Rough selection L=1.5 liters, fine selection L=0.75 liters. Rough selection t=2 points, fine selection t=1 point.

[0018]
[0019]
[0020] It is known from Table 1 that the collection ability of DY15 to molybdenum concentrate is obviously higher than that of YC agent. The concentrate recovery rate reached 83.58%, the medium ore recovery rate reached 8.48%, a total of 92.06%, while the use of YC chemicals was only 90.02%, an increase of 2.04 percentage points under the same conditions. Using polyethylene glycol as a cross-linker does not work well, and using acrylic acid as a cross-linker does not work.
Embodiment 2
[0022] Conditions: 500g of andesite-type molybdenite, grade 0.8%, grinding fineness -400 mesh 80%. Rough selection L=1.5 liters, fine selection L=0.75 liters. Rough selection t = 2 minutes, selection t = 1 minute, the mixing time is 1 minute, the process is the same Figure 1 , Molybdenite flotation test results are shown in Table 2.

[0024]
[0025] It is known from Table 2 that the collection ability of DY15 collector on molybdenite is better than that of YC agent, and the recovery rate is 6.88 percentage points higher under the condition of equivalent concentrate grade. Using polyethylene glycol as a crosslinker does not work well, and using acrylic acid does not work.
Embodiment 3
[0027] Conditions: Granite porphyry molybdenite 500g, grade 0.8%, grinding fineness -400 mesh 80%. Rough selection L=1.5 liters, fine selection L=0.75 liters. Rough selection t = 2 minutes, selection t = 1 minute, the mixing time is 1 minute, the process is the same Figure 1 , Granite porphyry molybdenite flotation test results are shown in Table 3.
[0028] -400 mesh granite porphyry type molybdenite flotation test results Table 3
[0029]
[0030] It can be known from Table 3 that in the flotation of granite porphyry molybdenite, the flotation effect of DY15 collector is also better than that of YC agent, and the difference is obvious, and the recovery rate is about 8.89 percentage points higher. Both polyethylene glycol and acrylic acid did not achieve the effect of improving the recovery rate.
