Embodiment 1
[0026] This embodiment includes the following steps:
[0027] Step 1. Grinding the bonded copper oxide ore after crushing to obtain mineral powder, then uniformly mixing the mineral powder and water to obtain raw ore pulp; the mass concentration of mineral powder in the raw ore pulp is 36%, and the combined The mass content of copper in the copper oxide ore is 1.08%, the bonded phase occupancy rate of copper in the bonded copper oxide ore is 44.76%, the mass content of iron in the bonded copper oxide ore is not less than 15%, and the particle size of the ore powder is - 0.074mm mineral powder accounts for 60% of the total mass of said mineral powder;
[0028] Step 2, using a wet-type weak magnetic field magnetic separator to carry out weak magnetic separation of the raw ore pulp described in step 1, and separate the weak magnetic separation concentrate and weak magnetic separation tailings, and then shake the weak magnetic separation tailings. The gravity separation concentra...
