Abstract

The basic purpose of this research was to study the investigation of CYANIDE ADSORPTION on ACTIVATED CARBON surface from tailing dam water in AGHDAREH-TAKAB gold processing refractory in West Azerbaijan. In this refractory industrial ACTIVATED CARBON is used for the ADSORPTION of gold complexes. Then in this work the same ACTIVATED CARBON was used for absorbing the CYANIDE from the tailing dam water. Solution pH, ADSORPTION time, amount and size of ACTIVATED CARBON and temperature are some important parameters in the ADSORPTION mechanism. ACTIVATED CARBON was used in two fraction (6-12) mesh and (100-150) microns in tests. The optimum conditions (500-1000) microns fraction were obtained in pH=12, ADSORPTION time=35 minute, temperature less than 30, ACTIVATED CARBON=34(gr/l) and ADSORPTION percent=80. For (100-150) microns were obtained in pH=11.5, ADSORPTION time=35 minute, temperature less than 30, ACTIVATED CARBON=38(gr/l) and. ADSORPTION percent=82. Copper sulfate increasing caused an increase in the ADSORPTION percentage. The (500-1000) microns fractions follow from freundlich isotherm rather than Longmuir isotherm and (100-150) microns fraction are due to both isotherm.
