Froth Flotation Process Used In The Lead Zinc Sulfide Ore

This froth flotation process is applicable to lead and zinc sulfide minerals with different flotation behaviors due to different inset components, which can obtain the better flotation indexes while reducing the configuration volume of the flotation machine, reduce metal circulation and loss, decrease the flotation reagent consumption and ...

Modeling The Sauter Mean Bubble Diameter In Mechanical

There currently exists no available model for predicting the Sauter mean bubble diameter, D32, from the key process variables for mechanical flotation machines. This is seen as a significant shortcoming since flotation is a surface area (of bubbles) dependent process, the key metric being the bubble surface area flux, Sb, defined as 6 Jg/ D32, where Jg is the superficial gas velocity.
