摘要

Flotation is used in various fields ranging from wastewater treatment to ore processing in mining. Flotation is largely based onaeration and oxygen transfer. By using water engineering principles, a significant amount of air bubbles can be transferred tothe water in a short time. Today, conduits are the most important hydraulic structures used in aeration. The air taken from theatmosphere with the help of the air hole opening into the conduit is given to the water in bubbles. A large number of bubblesin the form of air flow accelerates the transfer of oxygen. As a result of these processes, flotation efficiency increases parallelto the aeration efficiency. In this study, a pressurized conduit integrated into the flotation cell and air bubbles are introducedinto the system. In the pilot scale flotation system, the effect of various physical parameters such as conduit opening ratio, airintake hole length and diameter on flotation efficiency are investigated. Results indicate that this new system provides a veryhigh amount of air bubbles to the flotation cell and the physical properties of the air intake hole has a significant effect on theamount of air entering the column (cell).
