Flotation Technique for Fecal Parasite Concentration ...

This technique is predominantly used in parasitology laboratories. By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.. The most commonly used reagent is zinc sulphate.Operculated eggs as well as schistosoma and infertile Ascaris ...

Testing of New Collectors for Concentration of Fluorite by ...

In this study, two new collectors for fluorite flotation DP-OMC-1033 (DP-I) and DP-OMC-1234 (DP-II) were tested and compared with oleic acid (OA), sodium oleate (SO) and potassium oleate (PO). According to fluorite grade and fluorite metallurgical recovery, the effect of each collector was determined, both in mechanical and pneumatic cell flotation.
