Removal of antimony (Sb(V)) from Sb mine drainage
The principal compound in the precipitate was stibnite (Sb2S3) at pH 7 and pH 9. The Sb(V) removal mechanism is sulfate-reduction and sulfide oxidization-precipitation, different from the conventional SRB-precipitation processes for heavy metals. The Sb(V)/sulfate ratio is noted an essential parameter affecting the Sb removal efficiency from SMD.
Precipitation and ageing of antimony (III) sulphide
16/12/1981· Antimony (III) sulphide has been prepared by precipitation from aqueous solution, under different conditions of concentration, temperature, pH and ageing time. The phase composition, crystallinity and particle size of the precipitates have been studied by X-ray diffraction, electron microscopy and vacuum microbalance technique, and correlated with conditions of precipitation.

iron precipitation of antimony
Sulfide ore or liquated antimony sulfide is reduced to metal by iron precipitation. Antimony trioxide may be volatilized from sulfide ores, and can be reduced to metal with charcoal in reverberatory furnaces. Antimony product may also be produced by blast furnace smelting or hydrometallurgical methods.
Antimony Passive Treatment by Two Methods: Sulfate
In the other treatment method, antimony was removed through precipitation as antimony sulfide (stibnite) in a sulfate-reducing bioreactor. Each system consisted of a 1000 liter plastic tub, filled with the treatment media. The loading ratio of iron oxyhydroxide in the adsorption chamber was 253 grams of precipitate per liter of water. The bioreactor contained equal parts
Recovery of antimony compounds from alkaline sulphide
10/07/2016· In the precipitation process, the addition of hydrogen peroxide to the alkaline sulphide leachate prompts the precipitation of antimony as NaSb(OH) 6. The result also implies that < 100% of stoichiometric hydrogen peroxide is required to completely oxidize the total amounts of both Sb 3 + and S 2 − in the solution and to quantitatively precipitate > 90% of the antimony
Sulphide precipitation – Mine Closure
Sulphide precipitation is applicable for metal containing mine waters when very low effluent concentrations are required or when selective metal removal and recovery are needed. The process can remove lead, copper, chromium (VI), silver, cadmium, zinc, mercury, nickel, thallium, antimony, and vanadium (INAP 2009). Advantages of sulphide precipitation (e.g. Kuyucak
