flotation concentration method

Flotation Technique for Fecal Parasite Concentration Methods

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 ...

1 Froth Flotation – Fundamental Principles

several methods that are useful for examining froth flotation processes: (a) Ratio of Concentration , the weight of the feed relative to the weight of the concentrate, The Ratio of Concentration is F/C, where F is the total weight of the feed and C is the total weight of the concentrate.
