  • Vacuum refining copper melts to remove bismuth, arsenic ...

    Arsenic and antimony removal were quite slow: 0.2 to 3 x 10-5 and 0.1 x 10-5 m/s, respectively, and evaporation controlled rates of refining. It is shown that, at typical concentrations of these elements in copper, monatomic evaporation is the predominant evaporation mechanism.

  • Effect of pH on the removal of arsenic and antimony using ...

    Dec 20, 2000· The removal of arsenic and antimony compounds is almost proportional to the removal efficiency of NaCI. The removal of As(V) and Sb(V) is much higher than As(III) and Sb(III) over the pH range 3-10. The effect of solution pH on the removal of arsenic using RO membranes was strongly affected by the solution pH, especially As(III), whereas the ...

  • Arsenic and Antimony Removal from Drinking Water by ...

    The media life for arsenic and antimony removal relies on factors, such arsenic and antimony concentrations, raw water pH, and the presence of other competing anions. Both media have a pH operating range of 5.5 to 8.5 with the removal capacity increasing with decreasing pH. Competing anions such as silica and phosphate are known to adsorb onto ...

    Mar 29, 2011· Anode slime is an important material of recycling precious metals. Up to now, treating the arsenic- and antimony-rich anode slime by conventional processes has the following problems: its economic and environmental effect is less than satisfactory, and the removal effect of arsenic and antimony from anode slime in present processes is not all that could be desired. Therefore, vacuum …

    Fe:As ratios up to 100 were evaluated by adding ferric chloride. Further, economic analysis showed that arsenic and antimony removal up to a point is more cost-effective using a CF process rather than AM, so early pilot testing focused on maximizing removal of arsenic and antimony. Figure 2 shows arsenic removal at increasing Fe:As ratios.

    The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in the periodic table. It is speculated that antimony could be a natural contaminant with arsenic in some drinking waters. Soluble forms of antimony (and arsenic) tend to be quite mobile in water, whereas less soluble species are adsorbed into
