the flotation circuit configuration is not very se nsitive to stage recovery [9,19 ]. The overall output suggests that choosing the best flotation circuit is not sensitive to the stage recovery, and as a result, only approximate values of the recovery can be used to select the optimal flotation circuit [6,9,20 ].

The methods most frequently used to recover parasite eggs and oocysts are flotation techniques that rely on the differences in the specific gravity (SG) of the egg(s), fecal debris, and flotation solution. The SG of most parasite eggs is between 1.05 and 1.23.1 For parasite eggs to float, the
