In the early 1950s, however, interest in the metallurgical application of activated carbon was revived when a procedure was developed by Jack B. Zadra at US Bureau of Mines for the elution and electrowinning of gold and silver adsorbed on carbon granules, which allowed re-use of the carbon, and the utilization of the process as a concentration ...

Jan 01, 2016· Subsequently, Zadra et al. (1952) developed an elution process using caustic cyanide with integrated electrowinning, which would ultimately become the first truly successful, commercial elution process (Zadra Process). It was tested at the San Andreas Mine (Zadra et al., 1952) and would eventually replace the ammonia process at the

The zadra operates in fairly elevated temperature and hence you need less volume to handle. This means you got to place it after carbon circuit which adsorbs gold from cyanide solution and you then again treat this carbon with cyanide and caustic to desorb from carbon (less volume to handle). Enclosed image may be little help.
