活性炭是从含多种组分的氰化溶液中吸附金和银的最有选择性的一种吸附剂.这种氰化溶液是对矿物原料浸出后得到的,除金和银外还含有铜、锌、镍、钴、铁.为了从氰化溶液特别是从矿浆中提取金银,在选择活性炭时,不仅要考虑活性炭的吸附性质,还应注意吸附剂的强度,以防止金和银随炭屑损失. Activated carbon is the most selective adsorbent for the adsorption of gold and silver from a cyanide solution containing various components, which is obtained after the leaching of mineral raw materials, in addition to gold and silver, copper , Zinc, nickel, cobalt, iron.In order to extract gold and silver from the cyanidation solution, especially from the pulp, when selecting activated carbon, not only the adsorption properties of the activated carbon should be considered, but also the strength of the adsorbent should be paid attention to prevent the gold and silver Carbon loss.
