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

浮选用于从废水处理到采矿中的矿石处理的各个领域。浮选主要基于曝气和氧气转移。通过使用水工程原理，可以在短时间内将大量气泡转移到水中。如今，导管是用于曝气的最重要的水力结构。借助于通向导管的气孔从大气中吸收的空气以气泡的形式被送入水中。大量气泡以气流的形式加速了氧气的传输。这些过程的结果是，浮选效率与通气效率平行增加。在这项研究中，集成到浮选池中的加压导管和气泡被引入系统中。在中试浮选系统中，研究了导管开口率，进气孔长度和直径等各种物理参数对浮选效率的影响。结果表明，该新系统为浮选池提供了非常大量的气泡，并且进气孔的物理特性对进入塔（池）的空气量具有重大影响。
