Abstract:
Different parameters affecting the behavior of froth flotation of Jordanian tar sand, obtained from the
Dead Sea area, were studied. This study was performed in a modified fluidized bed floatator. The effects
of the addition of a flotation agent, NaOH, temperature and flotation time on the beneficiation of bitumen
in the froth were investigated. It was found that the beneficiation factor in the froth increased with the
increase of temperature and flotation time. However, the amount of base (NaOH) and the flotation agent
were found to have a negative effect on that factor. A regression model based on a full factorial experimental
design results was obtained with a significant correlation coefficient. The optimum beneficiation
factor was found to be 7.2 and the bitumen content in the froth was found to be 79% in the froth, which
was obtained at 0.2 gNaOH/L, zero agent, 80 C, and 30 min.
