· Sodium metabisulphite (MBS, Na 2 S 2 O 5) has been applied as a depressant for pyrite flotation in neutral to slightly basic pH conditions. When dissolved in basic solutions, MBS generates sulphite with sulphur in its oxidation state S(IV), following Reaction (1) ( DávilaPulido et al., 2011 ): (1) S 2 O 5 2 + H 2 O = 2 S O 3 2 + 2 H +

In the flotation separation of minerals, reagents containing a sulfoxy radical, such as sodium sulfite, sodium bisulfite and sodium metabisulfite (or alkali metal, alkaline earth metal or ammonium equivalents thereof), sulfur dioxide or other thionates are commonly used to improve the quality of the separation, particularly where sulfidic minerals such as chalcopyrite, pentlandite, pyrite ...
What Are Commonly Used Silver Extraction Processes?
· When using regulators such as sodium sulfite, sodium sulfate, and starch, attention should be paid to their dosages. If the amount is too large, it is not good for the silver extraction process. The suitable pulp pH value of silver flotation is 6 to 8. In actual production, it should also be adjusted according to the recovery of other minerals.

Flotation of sphalerite and pyrite in the presence of ...
activated pyrite, the effect of sodium sulfite on its flotation is not well documented in the literature and is the subject of this study together with its separation from sphalerite in mildly alkaline pH conditions. Several mechanisms have been put forward to explain the depression of the flotation of sphalerite by sulfites Misra et al., 1985 . They include:Ž. the formation of a zinc sulfite ...

Galena is depressed using sodium dichromate, sodium sulfite, polysaccharide (starch, dextrin) or even CMC. Addition rates of these depressants can be critical if any recirculating load is returned to the bulk rougher circuit. This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using ...

Flotation of sphalerite and pyrite in the presence of ...
· The effect of sulfite is more important on pyrite flotation than on sphalerite flotation, hence the better separation obtained in the presence of sodium sulfite. Sphalerite flotation slightly decreases with an increase in sodium sulfite concentration with recoveries (after 8 min of flotation) of 88% in the absence and 73% in the presence of 10 −3 mol dm −3 sodium sulfite.
