Froth flotation, either conventional or column, has been studied for phosphate upgrading. In this study, a reverse flotation scheme using either mechanical or column flotation was applied for the beneficiation of Al-Jalamid Saudi phosphate ores. It is classified as a sedimentary phosphate with calcite as main impurity calcareous type. The effects of different operating parameters were.

Jul 18, 2012018332The introduction of cyclonic circulation method is one of the most important developments in column flotation technology in the last years. In this study, effect of a cyclonic flotation column on the flotation performance of a siliceous phosphate ore was evaluated by the experiments on circulation pressures and circulation methods.

Performing of the flotation process in columns started in the year 1981. Since then, this new flotation technique became usual in many countries, including Brazil, where nowadays flotation columns are installed in plants for iron and phosphate ore concentration.

The super- natant contained approximately 0.25 to 0.50 ppm after 30 min standing. The supernatant was poured into the flotation column and was treated by foam flotation. HTA was added in pulses to maintain a stable foam. Only 0.01 ppm cadmium ion remained after 30 min flotation. The maximum removal decreased with increasing ionic strength.
