• Dry Stacking of tailings

    A typical moisture content of less than 20% is achieved by using a combination of belt, drum, horizontal and vertical stacked pressure plates and vacuum filtration systems (Martin, Davies et al. 2002). The term 'dry cake' or 'dry stack' is not entirely correct as the tailings have a moisture content several percent below saturation.

  • Large scale density gradation tests in compacted rockfills

    The large scale density tests are suggested to be conducted where at least 5 ft ( m) of rockfill has been placed and compacted. This allows for excavation through a single or multiple lifts for an overall density that is representative of the entire rockfill lift thickness.

  • Biosand Filter

    In general, slow sand filters have filtration rates of up to m/hour, as opposed to rapid sand filters which can see filtration rates of up to 21 m/hour. As its name suggests water in rapid filters passes quickly through the filter beds. Often, it has been chemically pretreated, so that little biological activity is present.

    Abstract: A closed form method is derived for the calculation of the power spectral density of linear filtered and nonlinearly distorted digital signals, applying to baseband signals as well as to linear modulated MPSK (phase shift keying) and MQAM (quadrature amplitude modulation) signals. A method of modeling the output of the transmitter as the output of a Markov chain, is .
