As flotation is a promising method for the removal of hydrophilic minerals compounds from soil, the role of many relevant parameters in soil decontamination is largely unknown. As a result the objective of this study was to test the feasibility of the flotation process for the removal of barium sulfate BaSO 4 compounds from contaminated soils
The important parameters of galena flotation were found to be collector type, dosage of zinc sulfate and dosage of starch that the appropriate parameters were determined using optimization experiments.
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.
These ores are beneficiated almost exclusively by flotation. Silver recovery during flotation, however, often is low, especially in the complex, fine-grained ores being developed in Alaska. Despite the economic importance of silver, little is known about the flotation behavior of silver-bearing minerals.

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.
