Plant Practice Of The Flotaire Column Flotation Machine For Metallic, Nonmetallic And Coal Flotation

This paper reviews commercial installations of FLOTAIRE Column Flotation Machines for metallic, nonmetallic, and coal flotation. Second generation FLOTAIRE Column Flotation Machines employ dual aeration systems to provide a mixture of air bubble sizes. Operating data presented in this paper shows that optimum grade and recovery relationship for each rougher, cleaner, and scavenger application are obtained by adjusting the ratio and volume of aspirator air bubbles and micro diffuser air bubbles.
