Abstract

The invention relates to a microscopic flotation bubble and particle mineralization process observation device and method in a flowing environment, belonging to the technical field of mineral flotation, including a turbulent flow field generating device capable of generating fluid intersection, and a bubble generating device is arranged in the turbulent flow field generating device Fixing device, turbulent flow field generating device is equipped with a particle input device with adjustable particle collision speed, and the bubble generating fixing device can clamp the generated air bubbles and place the bubbles at the fluid intersection of the turbulent field generating device, and the particles with adjustable particle collision speed The outlet of the input device is set directly above the bubbles, and a video observation device is installed outside the turbulence field generating device. The structure of the device is simple, the observation method is easy to grasp, and the operability is strong, which can provide help for the research of microscopic flotation bubbles and particle mineralization process in the flow environment.

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...
