elution and carbon regeneration in gold processing

In gold processing using cyanidation, analysis of solution elution and carbon reactivation circuits is Carbon activity testing is required to ensure that the barren carbon which is recirculated from the stripping-elution-regeneration phases of the process plant is capable of efficient adsorption.

Elution behaviour of metals from carbon

2009-10-15  ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.
