· Since potash ores contain water-soluble salts, flotation is carried out in a brine, which is about 7 mol/L of NaCl–KCl solution (Gaska et al., 1965). This high salt concentration significantly changes the interfacial water structure which affects collector adsorption at the surface of soluble salt minerals as well as at the air/brine interface.

Floatation technique. The principle is to use an emulsifying fluid of a greater specific gravity than that of the parasite eggs, which result in flotation of eggs in the solution. Thereby mere examination of the solution in the top most layer will clearly indicate the presence of …
Various concentration techniques like simple slat floatation, Zinc sulphate centrifugal floatation, formol-ether concentration and modified formol-ether concentration are employed for the diagnosis and the epidemiologic surveillance of parasitic infections in humans.

brine flotation concentration technique brine floatation method: An obsolete technique for concentrating parasitic ova from faeces. The most commonly used modern ova concentration methods in the USA are zinc sulphate centrifugal floatation technique of Faust and the formalin-ether sedimentation technique of Ritchie, and permutations thereof.
· The adaptation of flotation to the treatment of sulphide ores was a major step in the advancement of concentration technique. This process, coupled at times with some gravity and improvements in equipment efficiency, enabled the characteristics of concentrates to be steadily improved and ore reserves were greatly enlarged due to the consequent lowering of costs.

· Fecal flotation works on the principle that most parasite eggs (and some larvae) have a specific gravity of about 1.05 to 1.203 so they are less dense than flotation solutions. As a result, parasite eggs (and some larvae) will rise to the surface of the flotation solution.
· Reverse and direct flotation techniques have been used for the concentration of lithium minerals from pegmatite ores. In reverse flotation, gangue minerals are floated with cationic collectors to produce spodumene concentrate (as tailings) whereas in direct flotation, spodumene is floated with anionic collectors to reject gangue minerals to the tailings ( Redeker, 1979 ).
brine flotation concentration technique PRINCIPLE: The principle of floatation technique of feacal sample concentration is based on the use of saturated sodium chloride solution which has a specific gravity (relative density) that is higher than that of the parasites, their cysts, and eggs thus allowing them to float to the surface of the brine solution after been emulsified with it

former depends upon brine flotation, which process delete riously affects schistosome ova. The procedure of Helmy apparently bears some similarity to that developed by the present authors, but owing to the inaccessibility of his publica tion, a
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.
To faecal sediment made from centrifugal sedimentation technique add few ml of saturated common salt solution or any other floatation solutions and emulsify it. Fill up to one third of a small floatation tube with a thick emulsion of the faeces and fill the tube to its capacity with the same solution.
