| Abstract: | Adsorption capacity of ACFF in cyanide leaching liquor of gold ores was studied with cyanide leaching liquor of gold ores, containing various kinds of ions. The adsorbed leaching liquor was analyzed by atomic emission spectroscopy and colorimetric method. The contents of various kinds of ions in ACFF were determined with X-ray photoctron spectroscopy. ACFF not only adsorbed gold but also adsorbed arsenic, nickel, zinc, calcium, sulphur, bismuth, copper, iron, silver and cyanide anion. Atomic percentage of C and those of O, N, Zn, Fe increase and decrease respectively with the increase of the layer depth, while those of Ca, Au, Ag keep constant. |
