activated carbon selection gold recovery:

TECHNICAL PAPER - Purolite

2020-2-10 · Activated carbon is widely used for gold recovery from cyanide leach liquors via carbon-in-leach (CIL) or carbon-in-pulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon(6).

2019-4-3 · The purpose of this study is to prepare a new activated carbon from olive stones for use in gold recovery by carbon-in-leach (CIL) and carbon-in-pulp (CIP). The preparation method chosen was physical activation using steam. The effect of four process parameters: the residence time for carbonization, the activation temperature, the residence time for

Procedure & Method for Activated Carbon Testing

2016-10-23 · Metal recovery on carbon, after 24 hours, was essentially similar for all evaluated carbons. The tests conducted with Norit and Sorb-Tech carbons did indicate lower gold values in tail solids; however, over-emphasis on data credibility should be avoided due to analytical/assay accuracy constraints at low metal values.

By the time the pulp leaves the last tank in the adsorption cascade the concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. This represents a gold recovery
