Ultrasonic Elution Of Gold From Activated Carbon Request

Ultrasonic Elution Of Gold From Activated Carbon Request

both laboratory and plant loaded carbons were evaluated for their elution behaviour. It was found that the percent of gold eluted was greatly influenced by the temperature, acid concentration, and process for eluting gold-iodine complex from an ion-exchange resin, characterized by adding sulfuric acid and sodium nitrite to the gold-iodine complex adsorbed on the resin, and adding sodium sulfite as an eluant. the process is particularly useful for eluting gold-iodine complex adsorbed on strongly basic anion-exchange resin, such as washings resulting from the washing of leach residue
