Activated Carbon Stripping - Gold Refining Forum.com

Carbon reduces metals in a melt, it takes oxygen (or oxides) from the metals, making CO2 gas, even some of the metals that will oxidize easily in a melt, like copper and metals above copper in the reactivity series will reduce to metal, many of the reactive metals would need carbon to be melted, carbon is added to a flux, or sometimes the metal is melted with coke or some other carbon source.

Stripping Gold & Silver from Carbon - Chemistry

Stripping of gold and silver from carbon is effected by means of two main processes (AARL and ZADRA). The main rate-enhancing parameter in the stripping of gold and silver is temperature. A secondary rate-enhancing parameter is ionic strength. (1) Stripping is usually conducted within a solution containing sodium cyanide (0.1 – 0.5%) and caustic (1 – 3%). Several different analogous ...

Process for separately recovering gold and silver from

The remaining part of the carbon from stage 23 is passed successively to steps 22, 21 and 20 where gold is adsorbed in preference to silver. After the first stage 20, the carbon with adsorbed gold and some silver is passed to a gold stripping step 30 where gold is stripped from the carbon in any suitable manner.
