Density of Fluids - Essay ExampleThe solution preferred for this process was an pedestal metal salt or an alkaline earth metal salt of metatungstate. The solution should have a concentration of 1 to 80. The oxidant used is preferably selected from any of the following dichromate, chromate, nitrate, permanganate, peracid and perester group (Allies & Pagenkopf, 1998). These should have a preferred concentration of 0.05 to 0.5 weight %.The preferred alkaline salts are salts of lithium or sodium videlicet sodium dihydrogendodecawolframate or lithium dihydrogendodecawolframate .However, sodium dihydrogendodecawolframate is preferentially used. According to the invention bringing the solid miscellany into contact with the separating liquid is advantageous. These liquid should be of differing density in gradations of 0.005 g/cm.sup.3 to 0.1 g/cm.sup.3, preferably 0.05 g/cm.sup.3 to 0.01 g/cm.sup.3 (Jody, Daniels & Pomykala , 2003).Within a selected region of the density range the the sin king solid component is removed subsequently each stage.Besides this solution, other solution that have been used in separation of mixtures include fermentation alcohol or solutions containing ethanol, Ca(NO3)2, CaCl2ZnCl2.or NaCl. All thse method rely on the relative buoyancy of the separating
