At the same time, the bubbles are fully collided and contacted with the mineral particles through stirring, and the hydrophobic beryllium mineral particles will adhere to the surface of the bubbles to form mineralized foam, and the foam will float to the surface of the slurry to form a foam layer containing beryllium.

[0021] 2. The present invention can conveniently collect and process the floating foam layer through the collection and processing device, and conveniently send the foam layer containing beryllium mineral particles to the concentrator for concentration to remove excess water, and then filter the concentrated concentrate through the filtering equipment to obtain the final beryllium concentrate product.
