Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was modelled using the film-transfer model. A model of this form was also used for preg
For this ore the enhanced extraction was due to a combination of equilibrium and preg-robbing effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface
Jan 01, 2015· The optimum conditions for gold leaching were 1:12 mL of HCl 37% solution (v/v), 1:12 of NaOCl 12% solution (v/v), and 1:20 of solid-liquid ratio (w/v). The gold extraction yield was about 89%. Gold recovery by activated carbon adsorption was about 49.852%. Keywords: gold ore, leaching, hypochlorite-choride, activated carbon 1.
