An experimental device and method for observing the characteristics of flotation moving bubbles

Abstract

The invention discloses a flotation motion bubble characteristics observation experiment apparatus and a method, wherein the apparatus comprises a transparent bubble observer and a stirring barrel; the stirring barrel is connected to the inlet at the upper part of bubble observer through a feeding pump and a pipeline, and the outlet at the lower part of the bubble observer is connected with the stirring barrel through a discharging pump and a pipeline; the bottom of the bubble observer has an air chamber with micropore ceramic; the air chamber is connected with an air compressor through a tee, a valve and an air flow meter; the two sides vertical to the bubble observer have a light source and a high speed camera respectively; the high speed camera is connected to a computer through a data line; and the computer has a bubble image analysis software. According to the invention, the problem of difficult accurate measurement because of flotation bubble motion characteristics is solved; the experiment apparatus has the advantages of visualization, simple structure, simple operation and low operation cost etc.; the experiment apparatus can be widely applied in flotation laboratory tests and can be used for flotation classroom teaching.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device and method for observing the movement characteristics of flotation bubbles, which belong to the technical field of mineral flotation. Background technique [0002] With the large-scale development and utilization of mineral resources, the proportion of refractory fine-grained minerals has increased sharply, and the problem of fine-grained mineral separation has become more prominent. Flotation is the most commonly used method for fine-grained and fine-grained mineral separation. It uses the hydrophobicity of the mineral surface to make the moving air bubbles in the pulp selectively capture the target minerals. Therefore, bubbles play an important role in mineral flotation, and the motion characteristics such as bubble size, shape, speed, and bubble merger and rupture behavior directly affect the flotation speed effect. However, due to the complexity of the flotati...

AI Technical Summary

Problems solved by technology

However, due to the complexity of the flotation environment and the disorder and randomness of the bubble movement, there is no special device for observing the movement characteristics of the flotation bubbles, which leads to the lack of people's understanding of the flotation bubbles, which seriously affects the flotation process. Effective control of air bubbles is not conducive to the stability of flotation indicators
