Going for a Ride
| Division: | Physical & Mathematical Sciences | | Category: | Junior | | Region: | Northwestern Ontario | | City: | Thunder Bay, ON | | School: | Ecole Gron Morgon School | | Abstract: | Under the right conditions, hydrophobic particles or molecules may be removed from a solution by rising air bubbles. This process is known as flotation. The basic principle was demonstrated by dye flotation. The knowledge gained was applied to de-inking and mineral concentration. Flotation saves trees, energy, and protects our environment. |
