    Investigating The Effect Of Energy Dissipation On

    oscillating grid otation cell was limited to energy dissipations of up to 0.6 kW/m3, which is low when compared to 0.6 3 kW/m3 commonly used in both otation literature and industry. The current work uses a new oscillating grid cell which can operate at energy dissi-pations of up to 5 kW/m3. Quartz (sub 100 m) has been oated in the new cell at

    The Effect Of Energy Input On The Flotation Of Quartz In

    Oct 01, 2012 The oscillating grid flotation cell was based on the cell used by Changunda et al. (2008). A schematic of the oscillating grid cell is shown in Fig. 1. Physical specifications of the cell and grids are given in Table 1. The grids were cut from a single sheet of 1.5 mm stainless steel for added strength. Nineteen grids were mounted horizontally on the drive shaft to make up the grid stack.
