在金银的氰化冶炼中,利用离子交换树脂从氰化浸出矿浆或氰化浸出溶液里,通过离子交换反应,把溶解在其中的呈氰化络合阴离子的金银吸附在树脂上,这时发现了,弱碱性树脂用苛性钠,强碱性树脂用含有丙酮的盐酸或硝酸混合液洗脱吸附在树脂上的金银的方法。使用这些方法,吸附在树脂上的金银络合阴离子,因为其洗脱率相同而几乎同时被完全洗脱,金银以混合状态富集于洗脱液中。可是,一般天然产的金银矿,其金银含量比各有差异,含银率比含金率高达十数倍的情
In the cyanide smelting of gold and silver, ion exchange resin is used to adsorb silver and cyanide complex anion dissolved in cyanide leaching slurry or cyanide leaching solution onto the resin through ion exchange reaction Found that, weak alkaline resin with caustic soda, strong alkaline resin solution containing acetone or hydrochloric acid mixture of nitric acid adsorbed on the resin of gold and silver. Using these methods, the gold-silver complex anions adsorbed on the resin elute almost simultaneously at the same time because of their identical elution rates, and the gold and silver are enriched in the eluent in a mixed state. However, the general production of natural gold and silver mine, the gold and silver content than the difference, the rate of silver than the gold rate as high as several times the love
