Antimony and Arsenic Sulfide Scaling in Geothermal Binary Separation of Toxic Heavy Metals by Sulfide Precipitation

Although arsenic sulfide has higher solubility than antimony sulfide at low temperatures arsenic III sulfide can also precipitate and cause the same problems as stibnite Re evaluation of the thermodynamic data has led to more accurate data for stibnite equilibrium thermodynamics and Abstract Sulfide precipitation with Na2S is found to be highly effective to obtain a high degree of separation of heavy metal cations Cd Zn Cu and Pb and of the oxyanions of arsenic and selenium from complex wastewaters The metal separation characteristics are evaluated with a dilute synthetic mixture and with an actual copper smelting plant wastewater
