以国产活性炭纤维织物(炭布)代替活性炭吸附氰化液中的贵金属,本文主要研究了活性炭布吸附金、银的特性,即吸附速度和吸附容量与活性炭的比较;活性炭布与活性炭耐磨性的比较;活性炭布在氰化液中吸附金、银后做为阳极直接电解金的可能性的研究;电解后的炭布活化再生的研究。试验证明了活性炭布比颗粒活性炭吸附金、银具有许多优点;吸附容量大,吸附速度快,金属回收率高,使用寿命长,吸附了金、银的炭布可做为阳极直接电解金,省去了解吸工序,降低了成本。
The domestic activated carbon fiber fabric (charcoal cloth) instead of activated carbon adsorption of cyanide in the precious metal, the main study of the activated carbon cloth adsorption of gold, silver, that adsorption speed and adsorption capacity compared with activated carbon; activated carbon cloth and activated carbon wear resistance Of the activated carbon cloth in the cyanide liquid adsorption of gold and silver as the anode potential electrolysis of the direct study of electrolytic carbon cloth activated regeneration. The experiment proves that activated carbon cloth than the activated carbon adsorption of gold, silver has many advantages; adsorption capacity, adsorption speed, high metal recovery, long life, adsorbed gold and silver carbon cloth can be used as anode direct electrolysis of gold, province To understand the suction process, reducing costs.
