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
