The concept of membrane filtration provides high recovery efficiencies in the range of 82%-100%, 47%-99.5%, and 70%-99.5% for UF, NF, and RO respectively [169]. However, high energy consumption for pressure pumps during the process causes major economic and operational hindrance, specifically for RO application.

1.. IntroductionCyanidation is the method applied for recovery of gold from ores for a century. New cyanidation processes based on the recovery by adsorption to activated carbon of leach solutions containing low-grade (concentration) gold have been developed since 1970s and 85% of gold recovery is accomplished with this technique today (Gönen, 1992, Hendrix, 1994, Örgül and Atalay, 2002).

Spin recovery with the hands off the stick will be slower than with active control input. If the control surfaces are free-floating, natural stability is normally less than what it is with fixed control surfaces. For that reason, the Beggs/Mueller technique is less effective than actively ending the spin with both rudder and elevator.
