Sodium sulfite (sodium sulphite) is a soluble sodium salt of sulfurous acid with the chemical formula Na 2 SO 3.It is used as a preservative to prevent dried fruit from discoloring, and for preserving meats, and is used in the same way as sodium thiosulfate to convert elemental halogens to their respective hydrohalic acids, in photography and for reducing chlorine levels in pools.
This saves both time and money allowing robust flotation testing and optimization to occur with a minimal amount of ore sample used. A complete discourse on the computer software and statistical design of experimentation fundamentals for chemical processing is beyond the scope of this paper but pertinent references are provided for the reader ...
Fecal Flotation. Fecal flotation techniques use a variety of solutions, including sodium nitrate, zinc sulfate, sucrose, and sodium chloride, to identify parasite ova or larvae. The author prefers sodium nitrate as a fecal flotation solution because it will concentrate most nematode eggs and larvae, tapeworm eggs, flagellate cysts, and ...

Sodium hydrosulfide (NaSH) is a chemical reagent with numerous applications within predominately three (3) industries: Kraft Paper Milling. In Kraft, pulping sulfidity is controlled through the use of reduction furnaces which reduce sodium sulfate plus caustic soda to sodium sulfide.
General description Cubic crystals of sodium sulfide (Na 2 S) are extremely hygroscopic in nature and discolor on exposure to air. Na 2 S is soluble in water, slightly soluble in alcohol and insoluble in ether. Aqueous solutions of Na 2 S are strongly alkaline.. Application Na 2 S is used for H 2 S therapy, to study its effect on the prevention of diabetes in animals.

- The way all flotation techniques worm is that the weight of the parasite eggs is less than that of the flotation solution, so the eggs are suspended above the solution. Most fecal debris is heavier, so it sinks to the bottom. - The term used to describe the weight of an object as compared to the weight of water is SPECIFIC GRAVITY.

Sodium bisulfate, also known as sodium hydrogen sulfate, is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically either in the form of sodium hydroxide (lye) or sodium chloride (table salt).
Sodium dodecyl sulfate (SDS), synonymously sodium lauryl sulfate (SLS), or sodium laurilsulfate, is a synthetic organic compound with the formula CH 3 (CH 2) 11 SO 4 Na. It is an anionic surfactant used in many cleaning and hygiene products. The sodium salt is of an organosulfate class of organics.
In the presence of sodium sulfite, the amount of copper hydroxide increases on the pyrite surface, but not on the sphalerite surface . As a consequence, less cuprous xanthate is formed on the mineral surface after sulfite addition, and on pyrite than on sphalerite in agreement with the flotation results Fig. 2, Fig. 5.
Nov 04, 1975· The Separation of Boric Acid from Anhydrous Sodium Sulfate by Flotation: Boric Acid Produced By Reaction Between Refined Borax Pentahydrate And Sulfuric Acid EXAMPLE 1 A portion of Na 2 SO 4-- H 3 BO 3 equilibrium brine (2,390 grams) at 38°C. was heated to 80°C. in a three-liter beaker.

As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...

Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.Some commercial samples are specified as Na 2 S·xH 2 O, where a weight percentage of Na 2 S is specified.
The results demonstrated that the combination collector (sodium oleate: sodium dodecyl sulfate = 3:1) exhibited a better flotation performance and the maximum recovery increased to 83.18% at pH = 5 compared with single sodium oleate/sodium dodecyl sulfate. When sodium oleate was used as a collector, the maximum recovery reached 80% at pH = 5.

However, the flotation of gibbsite by using amines as collectors can not be applied for the south western Sinai gibbsite ore because a significant amount of quartz is present. Bulut and Yurtsever [8] found that, sodium dodecyl sulfate, as an alkyl sulfate collector, is effective in the acidic pH range during the flotation of alumina
