Abstract

Wastewater treatment with gold recovery through adsorption by activated carbon F. A. Batzias and D. K. Sidiras Department of Industrial Management, University of Piraeus, Greece Abstract The exploitation of gold mines of North Greece, which starts soon, and the continually increasing environmental concerns (leading to lower cyanide maximal permitted values in water), make the relative research of considerable interest. With respect to this, a refinement of the gold and silver recovery methods may contribute to cost minimisation of cyanide wastewater treatment. Several researchers have investigated the kinetics of the adsorption of gold and silver by activated carbon from cyanide, thiourea and chloride solutions. Very few works have been reported on gold adsorption by activated carbon from iodine/iodide solutions which can be obtained as a downstream leach liquor in wastewater treatment. This work investigates the kinetics of adsorption of gold from iodine solution by activated carb
