The accessibility of the ,silver and silver,-,gold, catalysts was determined from the thermogram area of the H 2 of TPD, assuming a stoichiometry H:Ag = 1 and H:Au = 1 . The TPD-H 2 method allows the calculation of the dispersion of the metal deposited on the surface of the support, as well as an estimate of the average size of the metallic crystals on the surface.

ground. The leaching chemical solution for gold and silver is commonly sodium cyanide. In dump leaching, which is used primarily for low-grade copper ore, the material to be treated is placed on unlined foundations (i.e., directly on the ground). The leaching chemical solution typically is sulfuric acid but sometimes is water.
