Embodiment 1
[0018] Andalusite ore strong magnetic-dense medium beneficiation process:
[0019] The first step of crushing: crush the andalusite ore until most of the andalusite has been dissociated from the andalusite ore, and the ore particle size is less than 8 mm;
[0020] The second step of magnetic separation: the crushed ore is removed by a strong magnetic separator to remove most of the weak magnetic gangue minerals such as biotite;
[0021] The third step of ore washing: the ore after magnetic separation is washed through the ore washing screen or other ore washing equipment to remove the part of the slime less than 0.5 mm;
[0022] The fourth step of beneficiation: ferrosilicon powder and water are mixed in a weight ratio of 2:1 to make a dense medium, and the ore after washing is mixed with the heavy medium, and is fed into the dense medium cyclone under a certain pressure for separation, and the ore is divided into Light products and heavy products, the light products become t...
