DESORPTION OF GOLD AND SILVER FROM ACTIVATED

2018-12-21 · Desorption is a phenomenon whereby a substance is released from or through a surface. The process is the opposite of sorption, either adsorption or absorption. In gold desorption, gold and silver ions are released from loaded carbons by contacted them with NaOH and NaCN-containing solvent. TheCN-of NaCN presses out the

Carbon Adsorption of Gold

2 天前 · The procedures and tests descriptions are given for the ultimate gold carbon loading tests and the dynamic gold carbon loading tests. A 4.5 parts per million gold solution was prepared by dissolving fine (-200 mesh) gold powder in a sodium cyanide solution made with deionized water at pH 10.5 (lime adjusted). This gold feed solution was fed by a metering pump at a rate of 2.5 ml/min. to each

The mechanism of elution of gold cyanide from

Numerous articles have appeared on the mechanism of the adsorption of gold cyanide onto activated carbon. In contrast, little information is available on the mechanism of elution of the adsorbed gold. It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly.
