Description

technical field [0001] The invention relates to an observation device and method, in particular to an observation device and method for microscopic flotation air bubbles and particle mineralization process in a flow environment used in industrial and mining research. Background technique [0002] Froth flotation is an efficient mineral separation technology that recovers valuable minerals from raw ore based on the difference in particle surface hydrophobicity. During the flotation mineralization process, the particles collide with the bubbles under the action of turbulence, and the hydrophobic particles are easy to adhere to the surface of the bubbles to form gas-solid aggregates, and float up to the foam layer with the bubbles, while the hydrophilic particles remain Tailings are formed in the pulp and discharged. [0003] Generally, the flotation mineralization process is divided into three distinct sub-processes, namely collision, adhesion and exfoliation. Clarifying the...
