Elution and Carbon Reactivation - Resource book

adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed. Loaded carbon is removed from the CIL circuit and the gold stripped from the carbon using a number of treatment steps. The result is a solution of high gold concentration (pregnant eluate).

BURNING ACTIVATED CARBON - Gold Refining Forum

Jan 20, 2017  The pictures are the ashed carbon and the slag that mixed with gold. How can I recover gold from both materials. I intially used borax and saltpeter to smelt the ash but we discovered the gold is mixed up with slag in particle form after grinding the slag into powder. How can I recover gold from both ashed carbon and slag.

Spark testing - Wikipedia

Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. These sparks can be compared to a chart or to sparks from a known test sample to determine the classification.
