flotation-vessel size). IGF was selected as an enhanced gravity-separation secondary-treatment technique, with microbubbles to help separate/lift con-taminants to the water surface for removal. Flotation was selected because of its lower cost relative to other secondary techniques, and IGF was selected over dissolved-air flotation because of its

Flotation as a Separation Process - Matis - - Major ...

The importance of the flotation process to the economy of the whole industrial world is considered enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high‐grade ores that could be processed by simple physical and mechanical methods have long since been used up (1).
