Having an essential change in the downcomer, Jet diffuser flotation column (JDFC) is a device which resembles Jameson flotation cell (JC) in terms of general operational principles. By taking into account the hydrodynamic and fluid mechanics principles (Şahbaz et al., 2013) downcomer was changed as a diffuser, therefore turbulence at the end of the downcomer was reduced to provide better aggregate stability and homogeneous dissipation of the bubbles in the separation tank.
According to experimental results carried out in pilot scale JDFC, not only higher flotation performance comparing with Jameson cell was obtained specifically for coarse particles, but also quiescent froth layer was acquired with the given conditions. In these tests, vertical pipe of JDFC having inlet diameter of 6 cm and outlet diameter of 11.5, 12.5 and 13.5 cm was used with separation tank having the diameter of 39 cm. By using the data, pilot scale JDFC having 4100 mm vertical pipe integrated with separation tank was produced and flotation tests were carried out by using the talc. Finally, the talc recovery obtained as about 90% by the use of JDFC for the particle size of 360 μm.
