    What Are Column Flotation Cells

    Feb 06, 2019 The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

    Column Flotation Theory And Practice

    Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are i) improved recovery, ii) higher grade, iii) lower capital and operating costs, iv) less wear and tear due to absence of moving parts and v) requirement of less floor space.

    A column cell consists of a vertical column into which air is added at the bottom using spargers (no impeller). Columns usually use wash water to prevent fine clays from being entrained into the clean coal froth. Gas compressors are usually required to provide the air flow and energy for air dispersion.
