    Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet (7.6m) to more than 50 feet (15.2m). The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth

    Sep 14, 2011 This has allowed a flotation cell to be modelled using the chemical reactor analogy; whereby the removal of solids from the pulp phase is defined by a first order rate equation. This means a bank of cells can be approximated by perfectly mixed CSTR's in series (Gaudin, 1957, Niemi and Paakkinen, 1969, Atkins et al., 1986, Yuan et al., 1996)

    The advantage of this new generation of solar cells is that they can be produced at low cost, i.e., potentially less than 1 U.S. $/peak watt. Some but not all OPV embodiments can avoid the expensive and energy-intensive high vacuum and materials purification steps that are currently employed in the fabrication of all other thin-film solar cells
