Mineral ore flotation process and apparatus
This patent describes a single step, continuous fractionating flotation process for separating a phosphate ore-containing material from a mixture thereof with a non-floatable particulate material it comprises introducing the mixture into a vertical flotation column containing a liquid, the column comprising at least one baffle means to promote turbulence therein; introducing a gaseous material into the vertical column below the point of introduction of the mixture; introducing the liquid into the column, the rate of introducing the mixture, the gaseous material and the liquid, and the baffle means being sufficient to create a substantial amount of turbulence in the vertical column to separate the phosphate ore-containing material from the non-flotatable particulate material; recovering the phosphate ore-containing material at an upper portion of the vertical flotation column; and recovering the non-floatable particulate material in a lower portion of the vertical column.
