Example Embodiment
[0033] Example 1
[0034] Using the Inner Mongolia 801 ore containing rare metal zirconium, uranium, niobium, beryllium, rare earth, and titanium minerals with a total amount of 5.00% and a quartz feldspar content of 90% as raw material ore, the process method of the present invention is used to perform the following process steps:
[0035] (1) Strong magnetic separation: take 1kg of raw material ore with a particle size of -0.5mm accounting for 50%, and carry out a closed-circuit magnetic separation process of one strong magnetic roughing and one strong magnetic sweeping. The rough beneficiation concentrate is a magnetic separation concentrate. The tailings are subjected to strong magnetic sweeping, and the concentrates are returned to the strong magnetic roughing process. The sweeping tailings are magnetic tailings. The magnetic field strength of strong magnetic roughing is 2.5T, and the magnetic field strength of strong magnetic scanning is 1.6T;

[0043] Example 2
[0044] Using the Inner Mongolia 801 ore containing rare metal zirconium, uranium, niobium, beryllium, rare earth, and titanium minerals with a total amount of 8.65% and a quartz feldspar content of 75.00% as raw material ore, the process method of the present invention is used to perform the following process steps:
[0045] (1) Strong magnetic separation: take 1kg of raw material ore with a particle size of -0.5mm accounting for 60.45%, and carry out a closed-circuit magnetic separation process of one strong magnetic roughing and one strong magnetic sweeping. The coarse beneficiation concentrate is a magnetic separation concentrate. The tailings are subjected to strong magnetic sweeping, and the concentrates are returned to the strong magnetic roughing process. The sweeping tailings are magnetic tailings. The magnetic field strength of strong magnetic roughing is 1.0T, and the magnetic field strength of strong magnetic scanning 3.5T;

[0053] Example 3
[0054] Using the Inner Mongolia 801 ore containing the rare metal zirconium, uranium, niobium, beryllium, rare earth, and titanium minerals at 10.25% and 82.67% of quartz feldspar as the raw material ore, the process method of the present invention is used to perform the following process steps:
[0055] (1) Strong magnetic separation: take 1kg of raw material ore with a particle size of -0.5mm accounting for 55.63%, and carry out a closed-circuit magnetic separation process of one strong magnetic roughing and one strong magnetic sweeping. The coarse beneficiation concentrate is a magnetic separation concentrate. The tailings are subjected to strong magnetic sweeping, and the concentrates are returned to the strong magnetic roughing process. The sweeping tailings are magnetic tailings. The magnetic field strength of strong magnetic roughing is 2.5T, and the magnetic field strength of strong magnetic scanning 3.0T;
