Cyanidation is widely used by many gold mining companies to dissolve gold from an ore or concentrate. After cyanidation the gold may be recovered from the solution by adsorption on activated carbon (McDougall and Hancock, 1981; Tsuchida et al., 1984; Bailey, 1987). The main carbon adsorption technologies are...
