Description

technical field [0001] The invention belongs to a modularized multi-level zone mineralization metallurgy pressurized mineralization system. Background technique [0002] The essence of mineralization metallurgy is to mineralize and convert the substances to be separated in the solution into hydrophobic complexes or complexes, and then separate them in depth by air flotation. Therefore, air flotation separation is of great significance in the process of mineralization metallurgy. The traditional air flotation is to introduce fine air bubbles into the water, a large number of air bubbles collide with the particles in the suspension, adhere to the suspended particles, and accumulate on the top of the liquid with the floating of the air bubbles, so as to achieve solid-liquid separation. The research shows that the size of the bubbles and the number of the bubbles play a key role in the mineralization transformation process of the material to be separated. However, the common a...

Problems solved by technology

However, the common air flotation equipment occupies a large area and has a limited amount of dissolved air, which limits the size of the bubbles and the rate of bubble generation, resulting in low air flotation separation efficiency.
